Plants and foods toxic to cats

Cats are curious: they nibble plants, explore counters and lick whatever lands on their fur. Some ordinary plants, foods and medicines can seriously poison them.

⚡ In short

  • Lilies are extremely toxic — pollen or vase water can cause kidney failure.
  • Paracetamol and other human painkillers can be fatal.
  • Never use permethrin dog flea products on cats.
  • If exposure is suspected, call your vet without waiting for symptoms.

  • Chocolate, coffee, tea
  • Grapes and raisins
  • Alcohol and raw yeast dough
  • Milk — most adult cats are lactose intolerant
  • Raw eggs and raw fish; cooked bones
  • Dog food isn't toxic but lacks the taurine cats need

Medicines and chemicals

  • Paracetamol (acetaminophen): a single tablet can be fatal.
  • Other human painkillers (ibuprofen, aspirin) damage stomach, kidneys and liver.
  • Dog flea and tick products containing permethrin cause tremors and seizures in cats — use only products labelled for cats.
  • Essential oils: tea tree, eucalyptus, peppermint and citrus oils; beware of diffusers.
  • Cleaning products, antifreeze, rat poison.

If your cat is poisoned

  1. Remove your cat and collect the plant or product.
  2. Note what, how much and when; keep the packaging or a photo.
  3. Call your vet or a pet poison helpline now — with lilies and paracetamol the first hours matter.
  4. Don't induce vomiting or try home remedies unless told to.
🚨Emergency signs: heavy drooling, repeated vomiting, tremors, seizures, breathing difficulty, blue or brown gums, weakness and not urinating.
