There is a moment every cat owner has: something hits the floor, the cat gets to it first, and you have about four seconds to decide whether this is a shrug or a phone call. This page exists for that moment. It is a complete reference to safe and toxic foods for cats — 183 individual items across nine categories, each with the reason it matters, the signs to watch for, and what to actually do.

If your cat has eaten something right now

Do not wait for symptoms, and do not try to make your cat vomit. Call one of these lines or your own vet immediately. Both services charge a consultation fee and both are staffed around the clock.

The short answer

The foods that send cats to emergency vets most often are onion and garlic in any form, chocolate, grapes and raisins, alcohol, caffeine, xylitol, raw bread dough, and human painkillers — especially paracetamol, which can kill a cat at a single tablet. Plain cooked meat, fish and egg are the safest human foods you can offer. Everything else sits somewhere in between, and the table below tells you where.

What to take away from this page

  • Cats are obligate carnivores. No human food is nutritionally necessary — treats should stay under 10% of daily calories.
  • The allium family (onion, garlic, leek, shallot, chive, spring onion) is the most common serious poisoning, and the signs often appear two to five days later.
  • Onion and garlic powder are more concentrated than the fresh vegetable and hide in stock cubes, gravy, crisps, baby food and spice blends.
  • Xylitol now appears in gum, mints, peanut butter, baked goods and some medicines. Read labels before sharing anything sugar-free.
  • Cats cannot process paracetamol. One standard tablet can be fatal, and the damage starts before any symptom shows.
  • Essential oils do not need to be eaten. A running diffuser is enough to poison a cat.
  • Never induce vomiting at home. Call a poison line or your vet and let them decide.

How to read this database

Every item is graded on a three-tier scale. The grades describe risk to a healthy adult cat of roughly four kilograms. Kittens, seniors, and cats with kidney, liver, heart or urinary conditions have less margin, so treat every "caution" entry as stricter in those cases.

Three-tier toxicity scale for cat foods safe caution and toxic

SAFE

Not toxic. Fine as an occasional treat in small, plain, unseasoned portions.

CAUTION

Not acutely poisonous, but carries real risk — fat, salt, sugar, choking, or harm with repeated feeding.

TOXIC

Actively dangerous. Contact a vet or poison line, in some cases before symptoms appear.

Important

Quantity, body weight and individual sensitivity all change the picture, and this page cannot account for your specific cat. It is a reference for orientation and prevention — not a substitute for a call to your vet. When you are unsure, call. Poison lines would far rather hear from you about a grape than see the consequences of waiting.

Meat, Fish & Eggs

Meat fish and eggs that are safe or toxic foods for cats

This is where most safe treats live. The rule is simple: plain, cooked, boneless, unseasoned. Nearly every problem in this category comes from what was added to the meat rather than the meat itself.

Food or item Verdict Why it matters Signs to watch for What to do
Chicken — cooked, plain, boneless SAFE Lean complete protein; the single best human-food treat for cats. None expected. Serve unseasoned and shredded. Keep to treat-sized portions.
Turkey — cooked, plain, skinless SAFE Same profile as chicken; highly digestible. None expected. Avoid the seasoned skin and any stuffing residue.
Beef — cooked, lean, plain SAFE Good protein; slightly richer than poultry. Loose stool if the cut is fatty. Trim fat. Small pieces only.
Lamb — cooked, lean, plain SAFE Digestible protein, useful for chicken-sensitive cats. None expected. Trim fat before serving.
Pork — cooked, lean, plain CAUTION Not toxic, but fattier and often heavily salted. Vomiting, loose stool. Only plain unseasoned cuts, rarely.
Bacon, ham, cured pork CAUTION Extreme sodium and fat load for a 4kg animal. Excessive thirst, vomiting, pancreatitis. Avoid. A single lick is not an emergency.
Processed deli meat, sausage, salami CAUTION Salt, nitrates, and very often onion or garlic powder. Vomiting, lethargy, pale gums if allium-containing. Avoid entirely — the seasoning is the real risk.
Liver — cooked, occasional CAUTION Vitamin A accumulates; chronic feeding causes bone disease. Stiffness, lameness, poor coat over months. No more than a thumbnail-sized piece weekly.
Raw meat CAUTION Salmonella, Listeria, Toxoplasma and E. coli risk to cat and household. Vomiting, diarrhoea, fever. Cook it. If raw-feeding, work with your vet on sourcing.
Cooked bones (any species) TOXIC Cooked bone splinters into sharp shards. Gagging, drooling, bloody stool, abdominal pain. Emergency. Never offer cooked bone of any kind.
Salmon — cooked, plain, boneless SAFE Omega-3s and complete protein. None expected. Fully cooked, no bones, no seasoning.
White fish — cod, haddock, cooked plain SAFE Lean and gentle on the stomach. None expected. Check meticulously for bones.
Raw fish CAUTION Contains thiaminase, which destroys vitamin B1. Wobbliness, dilated pupils, seizures in chronic cases. Cook it. Thiaminase is destroyed by heat.
Canned tuna in spring water CAUTION Not nutritionally complete; mercury accumulates; highly addictive to cats. Fussiness, refusal of complete food. A teaspoon occasionally at most. Never a meal.
Tuna in oil or brine CAUTION Added salt and oil compound the underlying problem. Thirst, loose stool. Choose spring water if offering tuna at all.
Sardines in spring water, no salt CAUTION Good omega-3s but salty and calorie-dense. Loose stool if overfed. Rinse. Quarter of a sardine, occasionally.
Shrimp and prawns — cooked, plain, deveined SAFE Lean protein most cats enjoy. None expected. Fully cooked, shell and vein removed.
Egg — cooked whole, plain SAFE Complete protein with good amino acid balance. None expected. Scrambled or boiled, no butter, oil or salt.
Raw egg white CAUTION Avidin binds biotin; salmonella risk on top. Poor coat and skin over time; acute GI upset. Cook eggs fully. Cooking destroys avidin.
Fish bones TOXIC Fine bones perforate the throat and gut. Gagging, pawing at mouth, drooling, blood. Emergency if swallowed. Debone all fish.

Dairy

Dairy products and lactose intolerance in cats safe food guide

The saucer of milk is the most persistent myth in cat ownership. Kittens produce lactase to digest their mother's milk and then stop. An adult cat given cow's milk is being handed a sugar it can no longer break down.

Food or item Verdict Why it matters Signs to watch for What to do
Cow's milk CAUTION Most adult cats lose lactase after weaning and cannot digest lactose. Diarrhoea, gas, cramping within 12 hours. Skip it. Water is what your cat actually needs.
Lactose-free cat milk SAFE Lactose removed, so the underlying problem is gone. None expected in most cats. Still calories — treat it as a treat, not a drink.
Goat's milk CAUTION Lower in lactose than cow's milk, but not lactose-free. Milder version of the same GI upset. Small amounts only, and only if tolerated.
Hard cheese — cheddar, parmesan CAUTION Low lactose, but very high in fat and salt. Loose stool, thirst. Pea-sized piece, useful for hiding tablets.
Soft cheese — brie, cream cheese CAUTION Higher lactose and fat than hard cheese. Diarrhoea. Avoid. Hard cheese is the better pill vehicle.
Blue cheese — stilton, roquefort, gorgonzola TOXIC The Penicillium mould produces roquefortine C, a neurotoxin. Tremors, twitching, vomiting, seizures. Call your vet. Do not treat as ordinary cheese.
Plain unsweetened yogurt CAUTION Live cultures pre-digest some lactose, so better tolerated. Mild loose stool. Half a teaspoon. Never sweetened or flavoured.
Greek yogurt, plain CAUTION Thicker and lower in lactose than standard yogurt. Mild loose stool. Same rule — plain only, tiny amount.
Cottage cheese CAUTION Moderate lactose, high salt in most commercial versions. Loose stool, thirst. Occasional teaspoon of the low-salt kind.
Butter CAUTION Almost pure fat; no nutritional case for it. Vomiting, loose stool, pancreatitis risk. Not worth offering. A lick is harmless.
Cream and whipped cream CAUTION Very high fat, plus lactose, plus sugar in whipped versions. Diarrhoea, weight gain. The classic saucer of cream is a myth. Skip it.
Ice cream TOXIC Combines lactose, sugar and fat — and often chocolate or xylitol. Depends entirely on flavour; chocolate and sugar-free versions are emergencies. Check the flavour. If chocolate or sugar-free, call your vet now.

Offering a cat a safe treat of plain cooked chicken by hand
A pinch of plain shredded chicken is a better reward than anything in the dairy aisle.

Fruits

Fruits safe for cats and toxic fruits like grapes and citrus

Cats are obligate carnivores and get nothing nutritionally essential from fruit. Most will ignore it. The category matters because of what is dangerous in it — grapes and raisins above all.

Food or item Verdict Why it matters Signs to watch for What to do
Grapes TOXIC Cause acute kidney injury by an unidentified mechanism. No safe dose is known. Vomiting within hours, then lethargy and reduced urination. Emergency. Call poison control immediately, even for one grape.
Raisins, sultanas, currants TOXIC Dried grapes — the toxin is concentrated, so the risk per gram is higher. Same as grapes, often faster onset. Emergency. Common in cereal, flapjacks and hot cross buns.
Blueberries SAFE Antioxidant-rich, low sugar, correctly sized for a cat's mouth. None expected. Two or three berries. Many cats simply ignore them.
Strawberries SAFE Non-toxic; high water content. None expected. Remove the leafy top. Small slice only.
Raspberries and blackberries SAFE Non-toxic in the quantities a cat would eat. Loose stool if overfed. One or two berries maximum.
Watermelon flesh, seedless SAFE Mostly water; useful in hot weather. None expected. Flesh only. Rind and seeds are a blockage risk.
Cantaloupe and honeydew melon SAFE Non-toxic. Some cats are strongly drawn to melon. None expected. Small cubes, rind removed.
Banana SAFE Non-toxic but high in sugar for an obligate carnivore. Loose stool if overfed. A slice the size of a fingernail.
Apple flesh, peeled, deseeded SAFE The flesh itself is harmless. None expected. Remove every seed and the core first.
Apple, pear and cherry seeds; peach and plum pits TOXIC Contain cyanogenic glycosides that release cyanide when crushed. Rapid breathing, bright red gums, collapse. Emergency. Whole swallowed pits are also a blockage risk.
Pear flesh, deseeded SAFE Non-toxic. None expected. Small piece, no seeds.
Peach and plum flesh CAUTION Flesh is safe; the pit is both toxic and obstructive. None from flesh alone. Cut the flesh away from the stone completely.
Cherry flesh CAUTION Flesh is safe; stems, leaves and pits are not. None from flesh alone. Not worth the handling risk. Choose berries instead.
Orange, lemon, lime, grapefruit TOXIC Citric acid and the essential oils limonene and linalool irritate and depress the nervous system. Drooling, vomiting, diarrhoea, tremors, skin irritation from peel oil. Keep peel and juice away. Most cats avoid citrus by smell.
Mango flesh SAFE Non-toxic; high sugar. Loose stool if overfed. Small cube, skin and stone removed.
Fresh pineapple flesh SAFE Non-toxic; high sugar and acidity. Mild GI upset. Fresh only. Canned pineapple is packed in syrup.
Avocado CAUTION Persin is a genuine risk to birds; cats are far less sensitive. The real hazards are fat content and the pit. Vomiting, loose stool. Choking or obstruction from the pit. Not recommended. Keep pits and skin out of reach.
Cranberries, fresh SAFE Non-toxic; sometimes used in urinary supplements. None expected. Fresh only — dried cranberries are sugar-loaded.
Coconut flesh and coconut milk CAUTION Not toxic but very high in fat and can contain added sugar. Diarrhoea, vomiting. Avoid. There is no benefit here.
Figs, fresh or as a plant TOXIC Ficin and ficusin cause irritation and photosensitivity. Drooling, vomiting, mouth irritation. Avoid the fruit and keep fig plants out of the house.
Dried fruit generally CAUTION Sugar is concentrated, and raisins hide in most mixes. Depends on which fruit. Check the ingredient list for raisins or sultanas before panicking.
Tomato, ripe red flesh CAUTION Ripe flesh is low risk; everything else on the plant is not. Mild GI upset from ripe flesh. Not recommended, but a nibble of ripe tomato is not an emergency.

Vegetables

Vegetables cats can eat and toxic vegetables including onion and garlic

The allium family — onion, garlic, leek, shallot, chive, spring onion — is the single most important group on this page. It appears in almost every savoury human dish, and the damage it causes is often not visible for several days.

Food or item Verdict Why it matters Signs to watch for What to do
Onion — raw, cooked, dried, powdered TOXIC Organosulfur compounds destroy red blood cells, causing Heinz body anaemia. Pale or yellow gums, weakness, rapid breathing, red-brown urine — often 2 to 5 days later. Call your vet. Delayed onset means a normal-looking cat can still be in trouble.
Onion powder TOXIC Dehydrated, so far more potent by weight than fresh onion. As above, from a much smaller quantity. Check baby food, gravy, stock cubes, crisps and pizza before sharing anything.
Garlic TOXIC Roughly five times more potent than onion by weight. As above, from a very small amount. Emergency. Ignore any online advice about garlic for fleas.
Leeks, shallots, spring onions, scallions TOXIC Same allium family, same mechanism. As above. Treat every allium as off-limits, cooked or raw.
Chives TOXIC Allium; commonly grown on kitchen windowsills within reach. As above, plus drooling. Move the pot. Grow cat grass instead.
Carrot — cooked, plain SAFE Non-toxic, fibrous, low calorie. None expected. Cook until soft and dice small. Raw carrot is a choking risk.
Green beans — cooked, plain SAFE Non-toxic; often used as a low-calorie filler. None expected. Plain and unsalted, chopped.
Peas — cooked or frozen-thawed SAFE Non-toxic; appears in many commercial cat foods. None expected. A few peas. Plain only.
Broccoli — cooked, plain SAFE Non-toxic; some cats enjoy the texture. Gas if overfed. Steam until soft. Small floret.
Pumpkin — plain, cooked or tinned SAFE Fibre can help both constipation and loose stool. None expected. Plain purée only. Pie filling contains nutmeg and sugar.
Butternut squash — cooked, plain SAFE Non-toxic, high fibre. None expected. Cooked, mashed, unseasoned.
Sweet potato — cooked, plain SAFE Non-toxic when fully cooked. Loose stool if overfed. Never raw. No butter or marshmallow topping.
Zucchini and courgette — cooked SAFE Non-toxic, very low calorie. None expected. Steamed and diced.
Cucumber SAFE Almost entirely water. None expected. Peeled, thin slices.
Bell pepper SAFE Non-toxic. Most cats show no interest. None expected. Small piece, deseeded.
Celery SAFE Non-toxic; some cats chew the stringy texture. None expected. Chop finely — the strings can catch.
Lettuce and leafy salad greens SAFE Non-toxic and high water content. None expected. Rinse well. No dressing.
Asparagus — cooked SAFE Non-toxic but tough. None expected. Cook until soft, chop small.
Sweetcorn kernels — plain SAFE Non-toxic; a common ingredient in commercial food. None expected. Off the cob. Cobs cause obstructions.
Potato — cooked, plain, peeled CAUTION Cooked potato is safe but nutritionally pointless for a carnivore. None expected in small amounts. No butter, salt, oil or garlic. There is no reason to offer it.
Potato — raw, green, or sprouted; potato leaves TOXIC Solanine, a glycoalkaloid that affects the nervous system and gut. Drooling, vomiting, diarrhoea, weakness, slow heart rate. Call your vet. Store potatoes out of reach and discard green ones.
Tomato plant — leaves, stems, unripe green fruit TOXIC Tomatine and solanine, concentrated in the green parts. Drooling, vomiting, lethargy, weakness. Call your vet. Keep tomato plants away from cats.
Spinach CAUTION High in oxalates, which contribute to calcium oxalate stones. None acutely; a problem for cats with urinary or kidney history. Avoid entirely if your cat has ever had crystals or stones.
Rhubarb — stalks and especially leaves TOXIC Soluble oxalates bind calcium and damage the kidneys. Drooling, vomiting, tremors, kidney failure. Emergency. Leaves are far more dangerous than stalks.
Mushrooms — store-bought, plain, cooked CAUTION Cultivated species are not toxic, but offer nothing nutritionally. Mild GI upset. Not recommended, but not an emergency.
Mushrooms — wild or unidentified TOXIC Several species cause liver failure or neurological collapse. Vomiting, drooling, jaundice, seizures, collapse. Emergency. Photograph the mushroom and go to the vet immediately.
Garlic or onion in baby food, stock, gravy, sauce TOXIC The most common route of accidental allium poisoning in cats. As with onion — often delayed by days. Read every label before sharing human food.
Beetroot — cooked, plain CAUTION Non-toxic but high in oxalates and sugar. Red urine that mimics blood and causes needless panic. Skip it. Not worth the false alarm.

Onions garlic and grapes left on a kitchen counter near a cat
The most dangerous configuration in any kitchen: allium, grapes and chocolate on an unattended surface.

⚠ Warning

Allium poisoning is delayed. A cat that eats onion on Monday can look completely normal until Wednesday or Thursday, when the destroyed red blood cells finally show as pale gums, weakness and dark urine. Never use "it seems fine" as a reason not to call. Tell your vet what was eaten and when, even if your cat is behaving normally.

Grains, Nuts & Seeds

Grains nuts and seeds in a cat food safety guide

Plain cooked grains are harmless but pointless. Nuts are the real concern: high fat, choking-sized, sometimes mouldy, and in the case of peanut butter, a common hiding place for xylitol.

Food or item Verdict Why it matters Signs to watch for What to do
White rice — cooked, plain SAFE Bland and binding; often recommended after GI upset. None expected. Plain boiled only. Small spoonful mixed with protein.
Oatmeal — cooked in water, plain SAFE Non-toxic, digestible fibre. None expected. Water only, never milk, never sweetened.
Pasta — cooked, plain SAFE Non-toxic but nutritionally empty for a carnivore. None expected. No sauce. Almost every pasta sauce contains garlic or onion.
Quinoa — cooked, plain SAFE Non-toxic, complete plant protein. None expected. Rinse before cooking. Plain only.
Bread — plain, fully baked CAUTION Not toxic, but pure carbohydrate with added salt. None in small amounts. A corner is harmless. There is no reason to make it a habit.
Bread dough — raw, unbaked TOXIC Yeast ferments in the stomach, producing ethanol and expanding gas. Bloated painful abdomen, retching, disorientation, collapse. Emergency. This is one of the fastest-moving kitchen poisonings.
Macadamia nuts TOXIC Mechanism unknown. Well documented in dogs; treated as toxic to cats. Weakness, tremors, vomiting, hind-limb difficulty. Call your vet. Also a serious choking hazard.
Walnuts TOXIC Prone to Aspergillus mould producing tremorgenic mycotoxins. Tremors, seizures, vomiting. Call your vet, especially if the nuts were old or black.
Pecans CAUTION Same mould risk as walnuts, plus very high fat. Vomiting, tremors if mouldy. Avoid. Store nuts in closed containers.
Almonds CAUTION Not acutely toxic but hard, fatty and difficult to digest. Vomiting, choking, obstruction. Avoid. Bitter almonds additionally contain cyanogenic compounds.
Cashews, pistachios, hazelnuts CAUTION High fat, salt, and choking size. Vomiting, loose stool, pancreatitis risk. Avoid. Remove shells from reach — pistachio shells obstruct.
Peanuts — plain, unsalted, shelled CAUTION Technically a legume and not toxic, but fatty and a choking risk. Vomiting, choking. One crushed nut at most. There is no benefit.
Peanut butter TOXIC Many brands now contain xylitol, which is dangerous even in trace amounts. If xylitol-containing: vomiting, weakness, collapse, seizures. Read the label. If it lists xylitol or birch sugar, treat as an emergency.
Sunflower seeds — plain, shelled CAUTION Not toxic but high in fat; shells are indigestible. Vomiting, loose stool. Avoid. Shells are the bigger hazard.
Pumpkin seeds — plain, shelled SAFE Non-toxic; sometimes ground into supplements. None expected. Plain and unsalted, ground or whole in tiny amounts.
Sesame seeds SAFE Non-toxic in the trace amounts a cat encounters. None expected. Fine as an incidental ingredient.
Popcorn — plain, air-popped CAUTION Plain popcorn is not toxic; unpopped kernels break teeth. Choking, dental fracture. Avoid. Buttered and salted versions are worse.
Cereal and granola CAUTION Sugar, salt, and very often raisins or chocolate. Depends on the mix-ins. Check for raisins and chocolate before you worry about the cereal.

Human Snacks & Sweets

Human snacks and sweets that are toxic foods for cats

Two substances dominate this section: theobromine in chocolate and xylitol in sugar-free products. Xylitol is the one most owners have never heard of, and it now appears in gum, mints, peanut butter, baked goods and some medications.

Food or item Verdict Why it matters Signs to watch for What to do
Dark chocolate and baking chocolate TOXIC Highest theobromine concentration of any chocolate. Cats cannot clear it. Vomiting, racing heart, tremors, seizures. Emergency. Note the cocoa percentage and weight eaten before you call.
Milk chocolate TOXIC Less theobromine per gram, but a cat is small enough for it to matter. Vomiting, restlessness, rapid heart rate. Call poison control with the weight eaten.
White chocolate CAUTION Minimal theobromine, but heavy fat and sugar. Vomiting, diarrhoea. Still not a treat. Confirm it was genuinely white chocolate.
Cocoa powder and cacao nibs TOXIC More concentrated than most solid chocolate. As with dark chocolate, often faster. Emergency. Store baking supplies in closed cupboards.
Xylitol and birch sugar TOXIC Triggers a dangerous insulin release and can cause liver damage. Weakness, wobbliness, collapse, seizures within an hour. Emergency. Found in gum, mints, peanut butter, baked goods and some medicines.
Chewing gum and sugar-free mints TOXIC The most common household source of xylitol. As above. Emergency. Keep handbags and coat pockets closed.
Sugar-free sweets and protein bars TOXIC Frequently sweetened with xylitol. As above. Read the ingredient panel, then call your vet.
Hard candy and boiled sweets CAUTION Choking and dental risk; sugar has no place in a cat's diet. Choking, gagging. Keep out of reach. Check for xylitol.
Crisps, potato chips, salted snacks CAUTION High salt and fat; many are seasoned with onion or garlic powder. Thirst, vomiting. Allium seasoning is the real concern. Check the flavour. Cheese-and-onion is a different problem to ready salted.
Salted pretzels and crackers CAUTION Sodium load is significant for a small animal. Excessive thirst, vomiting. Avoid. Fresh water should be freely available.
Cookies, biscuits, cake, frosting CAUTION Sugar, butter, and often chocolate, raisins or nutmeg. Depends on the ingredients. Identify the mix-ins first — those decide whether this is urgent.
Marshmallows CAUTION Pure sugar and gelatine; significant choking risk. Choking, GI upset. Avoid entirely.
Fried and fast food CAUTION Fat load can trigger pancreatitis; heavily salted and seasoned. Vomiting, abdominal pain, lethargy. Avoid. Pancreatitis is painful and expensive.
Table salt in quantity TOXIC Causes hypernatremia — sodium poisoning. Vomiting, extreme thirst, tremors, seizures. Call your vet. Never use salt to induce vomiting.
Playdough and salt dough ornaments TOXIC Extremely high salt concentration. As with salt poisoning. Emergency. A seasonal hazard worth knowing about.
Nutmeg-containing baked goods TOXIC Myristicin affects the nervous system. Disorientation, rapid heart rate, high blood pressure, seizures. Call your vet. Common in pumpkin pie and eggnog.
Raw cookie dough TOXIC Combines raw egg, raw flour and often chocolate; yeast doughs ferment. Bloating, vomiting, disorientation. Emergency if it was a yeast dough.
Chocolate-covered raisins TOXIC Two separate serious toxins in one item. Vomiting, then kidney signs over 24 to 72 hours. Emergency. Mention both components when you call.

Drinks

Drinks safe and unsafe for cats including water milk coffee and alcohol

Water is the only drink a cat needs. Everything else in this section is either unnecessary or dangerous, and caffeine and alcohol are dangerous at volumes a cat could easily reach on a coffee table.

Food or item Verdict Why it matters Signs to watch for What to do
Fresh clean water SAFE The only drink a cat genuinely needs. None. Multiple bowls away from food. Refresh daily.
Bone broth — no onion, garlic or salt SAFE Encourages fluid intake in cats that dislike drinking. None expected. Home-made or a cat-specific product. Almost all supermarket stock contains onion.
Lactose-free cat milk SAFE Formulated so the lactose problem does not apply. None expected in most cats. Counts toward daily calories. Treat only.
Cow's milk CAUTION Adult cats are generally lactose intolerant. Diarrhoea and cramping within hours. Offer water instead.
Almond, oat and soy milk CAUTION Not toxic, but sweetened versions may contain xylitol. Loose stool; xylitol emergency if present. Check the label. There is no benefit to offering it.
Coconut water CAUTION High in potassium, which matters for cats with kidney or heart disease. GI upset. Avoid.
Fruit juice CAUTION Concentrated sugar and acid; citrus juice is actively irritating. Vomiting, diarrhoea. Avoid. Citrus juice is worse than others.
Coffee, espresso and coffee grounds TOXIC Caffeine is a methylxanthine, like theobromine but faster acting. Restlessness, racing heart, tremors, seizures. Emergency. Used grounds in the bin still contain caffeine.
Tea — black, green, or any caffeinated TOXIC Same caffeine mechanism. Restlessness, rapid heart rate, vomiting. Call your vet. Do not leave brewed cups unattended.
Herbal tea — caffeine-free, plain CAUTION Depends entirely on the herbs; many are unsafe. Varies by ingredient. Avoid unless you have checked every herb in the blend.
Energy drinks TOXIC Very high caffeine plus taurine and sugar in unbalanced amounts. Severe agitation, racing heart, tremors, collapse. Emergency. The most concentrated caffeine source in most homes.
Cola and caffeinated soft drinks TOXIC Caffeine plus sugar plus carbonation. Restlessness, rapid heart rate, vomiting. Call your vet. Keep open cans off low tables.
Alcohol — beer, wine, spirits, liqueurs TOXIC Cats have almost no capacity to metabolise ethanol. Wobbliness, vomiting, low body temperature, slowed breathing, coma. Emergency. Even a small spill matters at cat body weight.
Sports and electrolyte drinks CAUTION Sodium and sugar formulated for humans, not cats. Vomiting, thirst. Avoid. Use vet-prescribed rehydration if needed.
Water from a tuna can CAUTION Spring water is harmless; brine is very salty. Thirst; fussiness afterwards. Occasional splash of spring water only.
Melted ice cream, milkshakes, hot chocolate TOXIC Chocolate content plus lactose plus sugar. Depends on chocolate content. Treat any chocolate drink as an emergency.
Diet drinks TOXIC Some contain xylitol rather than aspartame. Weakness, collapse if xylitol-containing. Check the sweetener on the label immediately.
Tap water in a shared dog bowl SAFE Perfectly fine and often preferred. None. Ensure your cat has a bowl a dog cannot guard.

Cat drinking fresh water from a fountain for healthy hydration
Cats evolved to get most of their water from prey, which is why many are poor drinkers. A fountain often helps.

Low water intake is a genuine health issue in cats, and it is one of the arguments made for wet food. If you are weighing that decision, our breakdown of wet versus dry cat food covers the moisture question in detail.

Herbs, Spices & Aromatics

Herbs and spices toxic to cats including chives and nutmeg

Essential oils deserve their own warning. Cats lack the liver enzyme that processes phenols and terpenes, and exposure does not require eating anything — a running diffuser is enough.

Food or item Verdict Why it matters Signs to watch for What to do
Chives TOXIC Allium family — the same red blood cell damage as onion. Pale gums, weakness, red-brown urine, often days later. Emergency. Remove pots from windowsills.
Garlic powder and granules TOXIC The most concentrated allium form in a kitchen. As with garlic. Check every seasoning blend, stock cube and rub.
Onion powder TOXIC Hidden in an enormous range of savoury products. As with onion, typically delayed. Read labels on anything you share.
Nutmeg TOXIC Myristicin is neurotoxic and cardiotoxic. Disorientation, rapid heart rate, high blood pressure, seizures. Call your vet. Peaks as a hazard around the holidays.
Bay leaf TOXIC Eugenol content plus a rigid leaf that can perforate the gut. Drooling, vomiting, abdominal pain. Count bay leaves in and out of the pot.
Marjoram TOXIC Causes GI upset and, with repeated exposure, heart effects. Vomiting, diarrhoea. Keep off the herb shelf your cat can reach.
Cinnamon — powder, sticks, or oil CAUTION Powder is low risk in traces; cinnamon oil is a genuine irritant. Mouth irritation, vomiting, low blood sugar with large doses. Keep the oil away entirely. A dusting of powder is not an emergency.
Black pepper CAUTION Irritant rather than toxic. Sneezing, mild GI upset. Season your own food after serving your cat's.
Chilli, cayenne, paprika CAUTION Capsaicin irritates the mouth, gut and eyes. Drooling, pawing at the mouth, vomiting. Avoid. Never use chilli as a deterrent spray.
Turmeric CAUTION Not toxic in traces but can interact with medication and stain everything. Mild GI upset. Only under veterinary direction.
Ginger — fresh, tiny amount CAUTION Sometimes used for nausea, but dosing in cats is not established. GI upset in larger amounts. Only if your vet has recommended a dose.
Rosemary, thyme, oregano, sage CAUTION Not acutely toxic as garnish, but the concentrated oils are. Vomiting, diarrhoea; oils cause tremors and drooling. Fresh sprigs are low risk. Essential oils are not.
Basil CAUTION Non-toxic in small amounts. Some cats chew the leaves. Mild GI upset if a lot is eaten. A leaf is fine. Keep the plant intact.
Parsley — curly, small amount CAUTION Curly parsley is low risk; spring parsley causes photosensitivity. Sun sensitivity, skin and eye irritation from spring parsley. Know which variety you grow before assuming it is safe.
Mint — garden mint, small amount CAUTION Garden mint in traces is tolerated; concentrated oils are not. Vomiting, diarrhoea. Fine as a plant, dangerous as an oil.
Pennyroyal TOXIC Pulegone causes liver failure. Vomiting, lethargy, jaundice, collapse. Emergency. Sometimes marketed as a natural flea remedy — it is not safe.
Essential oils — tea tree, eucalyptus, citrus, pine, peppermint, wintergreen, ylang ylang, cinnamon, clove TOXIC Cats lack the liver enzyme needed to process phenols and terpenes. Absorbed through skin and lungs as well as ingestion. Drooling, wobbliness, tremors, difficulty breathing, liver failure. Emergency. Stop any diffuser immediately and ventilate the room.
Diffused essential oils in the air TOXIC Airborne exposure is enough — the cat does not need to lick anything. Coughing, wheezing, drooling, wobbliness. Turn it off, open windows, move the cat to fresh air, call your vet.
Aloe vera TOXIC Saponins and anthraquinones cause GI and kidney effects. Vomiting, diarrhoea, lethargy, tremors. Call your vet. A very common houseplant.
Lemongrass — plant CAUTION The plant is mildly irritating; lemongrass oil is toxic. Vomiting, diarrhoea; oil causes severe signs. Plant is low risk in small nibbles. Oil is not.
Catnip SAFE Nepetalactone acts on scent receptors, not as a poison. Overexcitement or drooling if a lot is eaten. Safe. Non-addictive. Roughly a third of cats do not respond.
Silver vine and valerian root SAFE Alternative attractants for cats that do not respond to catnip. Mild overexcitement. Safe in normal toy quantities.
Cat grass — wheat, oat or barley grass SAFE Grown specifically for cats; aids hairball passage. Occasional vomiting, which is often the point. Keep a fresh pot available. It reduces interest in toxic houseplants.
Wheatgrass SAFE Same family as cat grass and equally safe. None expected. Rinse before offering if shop-bought.
Fresh coriander and dill, small amounts CAUTION Not toxic in garnish quantities. Mild GI upset. No benefit, but no cause for alarm.
Curry, chilli and spice blends TOXIC Almost universally contain garlic and onion powder. Allium signs plus GI irritation. Assume any savoury blend contains allium unless proven otherwise.
Stock cubes and bouillon TOXIC Onion, garlic and an enormous salt load. Allium signs plus excessive thirst. Never use to flavour a cat's food. Use plain bone broth instead.

Supplements, Vitamins & Medications

Human medications and supplements dangerous for cats

Human medication is the most lethal category on this page. Paracetamol in particular kills cats at doses a person would consider trivial, and the damage begins before any symptom appears.

Food or item Verdict Why it matters Signs to watch for What to do
Paracetamol and acetaminophen TOXIC Cats lack the enzyme to detoxify it. A single standard tablet can be fatal. Brown or blue-grey gums, facial and paw swelling, laboured breathing, dark urine. Emergency — go straight to a vet. Do not wait for symptoms.
Ibuprofen TOXIC Causes stomach ulceration and acute kidney failure at very low doses. Vomiting, black tarry stool, reduced urination, lethargy. Emergency. Never give human painkillers to a cat.
Aspirin TOXIC Cats clear salicylates extremely slowly, so doses accumulate. Vomiting, appetite loss, rapid breathing, bleeding. Emergency unless prescribed by your vet at a specific feline dose.
Naproxen and other human NSAIDs TOXIC Same ulceration and kidney injury pathway, longer acting. Vomiting, blood in stool, lethargy. Emergency.

What to do if your cat has eaten something toxic

The instinct is to search for symptoms and wait. That is the wrong order. For several of the substances on this page — paracetamol, grapes, alliums, xylitol — treatment is far more effective before signs appear, and by the time a cat looks unwell, the window has narrowed considerably.

What to do if your cat eats a toxic food step by step

01

Call before you do anything else

Contact a poison line or your vet immediately. Do not wait to see whether symptoms develop, and do not attempt to induce vomiting — salt, hydrogen peroxide and other home methods cause serious additional harm in cats.

02

Note the time and the amount

Write down when it happened and estimate how much was eaten. Treatment decisions depend heavily on both. Your cat's weight matters too, so have that ready.

03

Bag the packaging or the food

Keep the wrapper, the plant cutting, the pill bottle, or whatever is left. Ingredient lists and concentrations change what the vet does next — particularly with chocolate percentages and xylitol.

04

Get the carrier out early

If you are told to come in, you want the carrier ready rather than chasing a stressed cat around the house. Bring the packaging with you.

⚠ Warning

Never induce vomiting in a cat at home. Hydrogen peroxide causes severe stomach ulceration in cats, and salt causes sodium poisoning. Some substances — caustic products, petroleum distillates, sharp objects — cause far more damage coming back up. Vomiting is a decision for a veterinary professional with the full picture.

Signs of poisoning to watch for

Symptoms vary enormously by substance, and cats are famously good at masking illness. The signs below are the ones that most often bring a poisoning case to a vet. Any one of them, appearing suddenly and without explanation, is worth a phone call.

Signs of food poisoning in cats to watch for

Mouth and face

Drooling, foaming, pawing at the mouth, swelling around the face or paws, blue-grey or brown gums.

Breathing and chest

Rapid or laboured breathing, open-mouth breathing, coughing, wheezing.

Stomach and gut

Repeated vomiting, diarrhoea, blood in either, refusing food, a tense or painful abdomen.

Movement

Wobbliness, tremors, twitching, weakness in the hind legs, collapse, seizures.

Behaviour and alertness

Sudden lethargy, hiding, disorientation, unusual agitation, dilated pupils.

Drinking and urination

Excessive thirst, straining, producing very little urine, or urine that looks dark red-brown.

Hiding and sudden lethargy are easy to dismiss, particularly in a cat that sleeps a great deal anyway. If you are unsure what is normal for your cat, our guide to how much cats sleep covers where the line sits between normal rest and a warning sign.

The 10% rule for treats

The ten percent rule for cat treats and daily calorie portions

A typical indoor adult cat needs somewhere around 200 to 250 calories a day. Ten percent of that is roughly 20 to 25 calories — about the size of two or three small cubes of cooked chicken. That is the entire treat budget, and it includes everything: commercial treats, dental sticks, the milk in the saucer, and whatever fell off the counter.

The other 90% has to come from complete, balanced food, because that is where taurine, arachidonic acid, vitamin A and the other nutrients cats cannot synthesise actually come from. A cat filled up on chicken has been fed generously and nourished badly.

For the portion side of that equation — how much to feed, how often, and how to tell whether your cat is at a healthy weight — start with Cat Nutrition 101.

Common mistakes owners make

Assuming "a little bit" is always fine

It is for chicken. It is not for grapes, xylitol or paracetamol, where no safe threshold has been established for cats. Dose-dependence varies by substance, and the substances with no known safe dose are exactly the ones people tend to shrug off.

Forgetting that seasoning is the actual danger

A plain roast chicken breast is one of the safest treats available. The same breast cooked with garlic, onion, stock or a rub is not. Most allium poisonings do not come from a cat eating an onion — they come from a cat eating something an onion was cooked into.

Waiting for symptoms before calling

With alliums the signs can be days away. With paracetamol the liver damage is already underway before anything is visible. Treatment before symptoms is faster, cheaper and far more likely to work.

Trusting "natural" to mean safe

Essential oils, garlic-based flea remedies, aloe vera and pennyroyal are all natural and all dangerous to cats. Some of the most severe poisonings this page covers come from products marketed as gentle alternatives.

Applying dog information to cats

Cats and dogs metabolise substances very differently. Permethrin is a routine dog flea treatment and a life-threatening emergency in a cat. Paracetamol has a cautious canine dose and no safe feline one.

Leaving handbags and coat pockets open

Gum, mints, medication blister packs and vape refills all live in bags, and bags get left on floors and low chairs. It is one of the most common routes of accidental poisoning in a tidy home.

Frequently asked questions

Can cats eat cheese?

Small amounts of hard cheese are tolerated by most cats because it is low in lactose, and it is genuinely useful for hiding tablets. It is still high in fat and salt, so a pea-sized piece is the sensible ceiling. Blue cheese is a different matter entirely — the Penicillium mould produces roquefortine C, which is neurotoxic, and it should be treated as a call to your vet.

Is tuna bad for cats?

Not toxic, but not a food. Canned tuna is not nutritionally complete, mercury accumulates over time, and it is palatable enough that cats regularly start refusing their balanced food after a run of it. A teaspoon occasionally is fine. A tuna-based diet causes real deficiencies.

How much chocolate is dangerous for a cat?

It depends on the type and your cat's weight, which is exactly why poison lines want both pieces of information. Dark and baking chocolate carry the most theobromine per gram, milk chocolate less, white chocolate very little. Rather than guessing the threshold, weigh what is missing, check the cocoa percentage on the wrapper, and call.

Can cats drink milk?

Most adult cats cannot digest lactose, so cow's milk tends to cause diarrhoea and cramping rather than any benefit. Lactose-free cat milk avoids that problem but still adds calories. Water remains the only drink your cat actually needs.

My cat ate a small piece of onion and seems fine. Should I still call?

Yes. Allium damage to red blood cells is not immediately visible, and cats commonly look normal for two to five days before pale gums, weakness and dark urine appear. Your vet may simply want to run a blood test in a few days, but that decision should be theirs.

Are grapes really toxic to cats?

The kidney injury is best documented in dogs, but cases in cats are reported and no safe dose has been established for either species. Because the mechanism is still unidentified, poison control centres treat grape and raisin ingestion in cats as an emergency. There is no benefit to feeding them, so the safe course is straightforward.

Can I give my cat human painkillers?

No. Paracetamol is the clearest example — cats lack the enzyme needed to detoxify it, and a single standard tablet can be fatal. Ibuprofen, aspirin and naproxen all cause stomach ulceration and kidney injury at low doses. If your cat is in pain, that is a call to your vet, not a trip to the medicine cabinet.

Is it safe to use an essential oil diffuser around cats?

No. Cats lack the liver enzyme that processes phenols and terpenes, and exposure through the air and through grooming oil off their coat is enough to cause harm. Tea tree, eucalyptus, citrus, pine, peppermint, wintergreen and cinnamon oils are the most frequently implicated. If a diffuser has been running, turn it off, open the windows, move your cat to fresh air and call your vet.

What human foods are actually good for cats?

Plain cooked chicken, turkey, white fish, salmon and egg are the reliable options. They are complete proteins, well tolerated, and most cats find them highly motivating for training or medication. Everything else on the safe list is harmless rather than beneficial.

Should I be worried about my cat eating houseplants?

Often, yes. Lilies are the most serious — every part of a true lily, including pollen, can cause acute kidney failure in cats. Aloe vera, pothos, philodendron and sago palm are also common household hazards. Keeping a pot of cat grass available reduces the appeal of everything else considerably.

The bottom line

Most of what keeps cats out of emergency clinics is not knowledge of exotic toxins. It is a set of ordinary habits: reading the label before sharing, keeping handbags off the floor, counting bay leaves out of the pot, storing medication in a closed cupboard, and calling early rather than waiting to see.
