Can cats eat avocado?

Short Answer

Safety Summary

• ✔ Safe: No
• ⚠ Use caution: Contains persin — toxic to cats
• ✖ Toxic: Yes

Why

Avocado contains a fungicidal toxin called persin, found in the leaves, bark, skin, and pit — and in smaller amounts in the flesh. While cats are less sensitive to persin than some other animals, the risk is real enough that avocado should be avoided entirely. The high fat content of avocado flesh also poses a risk of pancreatitis and gastrointestinal upset even without the persin concern.

Portion Guidance

None. All parts of the avocado plant should be kept away from cats.

Risks & Symptoms

• Vomiting and diarrhea
• Difficulty breathing (in larger exposures)
• Fluid accumulation around heart and lungs
• Pancreatitis from high fat content

FAQ

A tiny amount is unlikely to cause severe harm but monitor closely for vomiting or lethargy. Contact your vet if concerned.

No — guacamole contains avocado, garlic, and onion, all of which are harmful to cats.
