Cat poisoning is mostly a story of ordinary households and extraordinary feline chemistry: things harmless to people and even dogs can be lethal to cats, whose livers lack certain detox machinery. The good news is that the danger list is short, the prevention is cheap, and the response, when it is ever needed, is a phone call made fast.
Poisoning outcomes are written by the clock: in the first hours, vets can make a cat vomit safely, bind toxins with activated charcoal, and start protective treatment before organs take damage. Wait for symptoms to prove the point and the best options have often expired.
So the rule is absolute: known or suspected contact with anything on this page is an immediate call to your vet or an emergency line, with the packaging or plant name in hand, even if the cat looks completely fine. Never wait to see, never make a cat vomit at home, and never dose anything as an antidote.
True lilies, the Lilium and Hemerocallis families, stargazers, tigers, Easter and day lilies, are catastrophically toxic to cats: every part, petals, leaves, stems, and infamously the pollen groomed off a brushed against coat, and even vase water. Tiny exposures can destroy kidneys within days.
The response is maximum urgency: any contact, however trivial it looks, is an immediate emergency visit, because early aggressive treatment protects kidneys and late treatment often cannot. The prevention is simpler still: lilies do not enter a cat household, full stop, and florists delivering gifts get told.
Permethrin, common in dog spot on flea products, is a notorious cat poison: applied to a cat by mistake, or transferred by cuddling a freshly treated dog, it triggers tremors, twitching, drooling and seizures, a genuine life threat with a completely preventable cause.
House rules write the prevention: dog products never touch cats, cat and dog treatments stored separately and labelled, packets read twice before applying anything, and treated dogs kept apart from cats until the product dries per the label. A twitching, tremoring cat with a treated dog in the house is an emergency drive, not a search engine session.
Human painkillers head the pharmaceutical danger list: paracetamol is lethal to cats in any dose, ibuprofen and aspirin are seriously toxic, and no human medicine of any kind is ever given to a cat on household initiative. Cats also poison themselves, batting dropped pills across the floor and licking spilled liquids.
The prevention is pharmacy discipline: medicines in closed cupboards, pills taken over a surface so drops are heard and found, and the vet consulted before any product, human or pet shop, joins a cat’s treatment. When in doubt about a chewed packet, ring with the name; identification is half the treatment.
Antifreeze deserves its infamy: ethylene glycol tastes sweet, cats drink spills willingly, and small volumes destroy kidneys with signs that begin as drunkenness and vomiting then falsely improve while damage proceeds. Garages and drives are the crime scene; autumn and winter the season.
The wider garage and garden list includes slug pellets containing metaldehyde, rodent poisons, which also poison cats who eat poisoned rodents, weedkillers, and creosote. Store all of it sealed and high, mop spills immediately, and choose pet safer formulations where they exist. Suspected antifreeze contact is a race: go immediately.
The food never list is short and worth memorising: onions and garlic in all forms, chocolate, grapes and raisins, alcohol, and anything sweetened with xylitol; while the houseplant list beyond lilies includes sago palm, dieffenbachia, and spring bulbs, with many others causing drooling and stomach upset rather than catastrophe.
The practical standard is not botanical scholarship but purchase discipline: check any new plant against a reliable toxic list before it comes home, keep bulbs and bouquets out of reach, and treat chewed mystery greenery as a phone call with a photo of the plant. Cats are not natural plant eaters; bored indoor cats are, which makes enrichment genuine poison prevention.
Unwitnessed poisonings announce themselves in patterns: sudden drooling, vomiting or diarrhoea, wobbliness and drunken walking, tremors or twitching, very fast or very slow breathing, drinking that suddenly doubles, gums an odd colour, or collapse, all arriving out of nowhere in a previously fine cat.
Sudden onset is the key word: dramatic, fast arriving illness earns emergency treatment as suspected poisoning while the cause is hunted. Bring context: new products used at home, gardens treated, a dog’s flea treatment date, missing pills, chewed plants. The history you carry often names the toxin faster than any test.
Poison prevention is one honest afternoon: florist ban on lilies communicated to the household and relatives, dog and cat products separated with a marker pen warning, medicines cupboarded, antifreeze and pellets sealed high, cleaning products closed away and floors dried before cats return, and houseplants checked against a list.
Finish by writing the emergency numbers where panic can find them: your practice, the nearest out of hours service, and the Animal PoisonLine. Our kitten proofing guide carries the wider audit; this page’s list is the chemistry chapter of it, done once and merely maintained forever after.
Cats Protection’s film on plants and flowers covers the ones that poison cats, lilies above all, the safer choices for a cat owning home and what to do if you think your cat has eaten something it should not. It is the plant chapter of this guide, shown with the actual flowers.

Cat poisoning prevention is a short list held firmly: no lilies in the house ever, dog flea products never near cats, human medicines locked away with paracetamol the deadliest, antifreeze and pellets sealed high, and new plants checked before purchase. The response is always the same: sudden dramatic illness or any known contact means ringing the vet immediately with the product or plant name, never waiting for symptoms and never home dosing. The golden hours belong to the fast.
Yes, now: kidney damage begins before symptoms show, and early treatment is the whole game with lilies. Fine today means nothing; treated today means everything.
No: the safe methods are veterinary, and folk methods, salt above all, cause their own poisonings. Your job is the phone and the car; the emptying stomach is the clinic’s job.
Several essential oils are genuinely toxic to cats through air, skin and grooming, tea tree notoriously. Keep oils off the cat and its reach, ventilate diffused rooms, and ask the vet before using any oil product in a cat home.
Dark chocolate carries the real risk and cats rarely volunteer for sweets, but a chocolate raiding cat still earns a phone call with the wrapper details. Dose and type decide, and the professionals calculate it in a minute.
Not toxic, just wrong: dog food lacks nutrients cats require, so theft is harmless and a diet of it is not. The genuine dog danger is the flea treatment, not the dinner.
Stop the grooming, that is the poisoning route: wrap the cat in a towel, ring the vet, and wash the paws or coat only as they direct, since some chemicals react with water. The towel buys time; the call decides the bath.
