Can cats eat Liver?

Caution

Caution. Small amounts of cooked liver are fine, but regular or large amounts cause vitamin A toxicity — a painful condition affecting the bones and joints.

If your cat has eaten liver

  1. No emergency for a single small amount of cooked liver.
  2. For cats on a liver-heavy home-made diet showing stiffness or reluctance to move, call your vet — this could be hypervitaminosis A.

What's the full picture?

Liver is very high in vitamin A. Cats eating a liver-heavy diet (or receiving liver as a daily treat) can develop hypervitaminosis A — excess vitamin A deposited in bones, causing painful bony growths on the spine and joints.

An occasional small piece of cooked liver is not a problem, but liver should never make up more than a small fraction of a cat's diet.

Raw liver carries the usual raw-meat bacterial risks. Cook it before giving any.

Safer alternatives

  • Plain cooked chicken or turkey

Questions owners ask

How much liver is safe per week?

A small piece (pea-sized to thumbnail-sized) of cooked liver once or twice a week is a reasonable ceiling for a healthy adult cat.

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.
