Can cats eat Grease / cooking fat?

No — dangerous

No. A cat that laps up concentrated cooking fat — from a roasting tray, frying pan, or dripping — is at serious risk of pancreatitis. UK roast-dinner fat is an under-recognised emergency cause.

If your cat has just eaten grease / cooking fat

  1. Move your cat away from the cooking fat or grease.
  2. Don't induce vomiting at home — this is dangerous in cats.
  3. Call your vet or out-of-hours emergency vet immediately.
  4. If you can't reach a vet, call the Animal PoisonLine on 01202 509000 — 24/7, charges apply.
  5. Note how much cooking fat or grease was eaten, when, and your cat's weight.

What's the full picture?

Cats that lick a cooled roast-dinner tray ingest a concentrated fat load that their pancreas can't cope with. Pancreatitis in cats is painful, debilitating, and sometimes fatal.

Animal fat (dripping, pork fat, duck fat) is the worst offender — it's almost pure fat. Vegetable oil from a chip pan is similar-risk.

Dispose of cooking fat in sealed containers in a lidded bin, not left in trays on a kitchen counter or floor. Even covered fat can attract cats.

Symptoms to watch for

12–72 hours
Vomiting, abdominal pain, lethargy, reduced appetite — pancreatitis developing.

About this guidance

Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.

This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.

Entries are reviewed and updated as new research emerges. Spotted an error? Let us know — corrections are investigated and applied within 24 hours. For more context on how we work, see about and our full disclaimer.
