Avocado

Toxic

Verdict

Avoid — persin in skin and pit is toxic; flesh is risky.

Toxic principle: persin
Source: ASPCA

Verdict

Avocado contains persin, a fungicidal toxin concentrated in the skin, pit, and leaves. The flesh contains lower levels but still poses risk. While cats are sometimes reported as more resistant to persin than birds or horses, persin can still cause vomiting, diarrhea, and myocardial damage. The large pit is also a choking and obstruction hazard. The high fat content can trigger pancreatitis. Best avoided entirely.

Symptoms to watch for

  • vomiting
  • diarrhea
  • abdominal discomfort
  • difficulty breathing (rare)
  • fluid accumulation around heart (rare, large doses)

What to do

Avoid feeding avocado in any form. If your cat consumed avocado — especially the pit, skin, or leaves — contact your vet. Monitor for GI distress and respiratory symptoms.
