While cats are less sensitive to persin than birds or horses, avocado can still cause significant GI upset. The pit is a serious obstruction hazard.

What It Is

Avocado contains persin, a fungicidal toxin present in all parts of the plant including the fruit, pit, leaves, and bark. The pit also poses a choking and intestinal obstruction risk.

Why It May Be Harmful

The toxic principle in avocado is persin (a fungicidal toxin). Persin is present in all parts of the avocado plant. It causes damage to the heart muscle and mammary tissue in some species. In cats, the primary concern is gastrointestinal irritation, though more serious effects are possible. The pit poses a choking and obstruction risk.

Signs of toxicity may include:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Loss of appetite
  • Difficulty breathing in severe cases

Timeline: Signs typically develop within a few hours.

Usually mild to moderate. The pit can cause life-threatening obstruction.

What to Do If Your Cat Eats It

  1. Contact a veterinarian or animal poison-control service for guidance.
  2. Remove any remaining substance from your cat's reach.
  3. Offer fresh water if your cat is willing to drink.
  4. Monitor for signs and contact a veterinarian if they develop or worsen.

Information to have ready when you call:

  • Your cat's age, approximate weight, and any health conditions
  • The name or type of avocado and the estimated amount consumed
  • When the exposure likely occurred
  • Any current symptoms your cat is showing
