Can Cats Eat Avocado?

Updated 18 October 2026 · Researched against PDSA, Cats Protection and International Cat Care guidance

Avocado contains persin, a compound that is most concentrated in the skin, stone and leaves. Cats are more tolerant of persin than some species, but 'more tolerant' is not 'safe', and the flesh is very high in fat.

A cat that eats a lot of avocado fat can develop pancreatitis — a painful inflammation that is genuinely serious in cats. The practical answer is that avocado offers a cat nothing and carries a real risk, so it does not belong in their bowl.

What to watch for in the UK

• Guacamole is worse than plain avocado: it usually contains onion, garlic, chilli, salt and lime.
• Keep the stone out of reach — it is a choking and blockage risk as well as a persin source.
• Avocado oil and avocado-based 'cat supplements' are marketing, not nutrition.
• Houseplants are covered separately in the toxic plants checklist.

If your cat has already eaten it

1. A small piece of flesh: watch for vomiting or diarrhoea.
2. Skin or stone, or guacamole: phone your vet.

Out of hours, use your practice's emergency number. If you can, take the packaging with you — the ingredient list often tells the vet more than the description does. This page explains risk; it cannot diagnose your cat, and it deliberately contains no doses or home treatments.

If your cat is already vomiting, see the cat vomiting guide and vomiting blood. For the wider red-flag checklist, use sick cat symptoms. If a plant rather than a food is involved, the toxic plants checklist is the right page.
