Can cats eat avocado?
Persin risk to cats is debated; the high fat, pit and skin make it a poor choice either way.
Portion: None recommended.
The short answer
Best avoided. Avocado contains persin, which is clearly toxic to birds, horses and ruminants. For cats and dogs the evidence is weaker, and mild stomach upset is the usual reported effect. The ASPCA still lists avocado among foods to keep from pets. The flesh is also very high in fat, which can cause vomiting or, in susceptible cats, pancreatitis. The pit is a choking and obstruction hazard, and guacamole contains onion and garlic.
Why the verdict
Persin is concentrated in the leaves, skin and pit, with lower levels in the ripe flesh. Species sensitivity varies enormously. Reports in cats are mostly mild GI upset, but data are limited. The more certain risks are fat (about 15 g per 100 g) and mechanical obstruction from the large pit. Because the evidence in cats is limited, we take the cautious position the ASPCA takes: keep it away from pets.
How to prepare it
- Don't offer avocado intentionally.
- Keep pits, skins and guacamole out of reach.
- Avoid avocado-based cat foods unless your vet approves.
Signs of trouble
- Vomiting or diarrhoea
- Abdominal pain or loss of appetite
- Straining or vomiting after swallowing pit fragments (possible blockage)
