Pecans can cause vomiting or diarrhea in cats due to their high fat content.
They may also pose a choking hazard or cause intestinal blockage if not properly chewed.
Suggestions
It’s best to avoid feeding pecans to your cat.
If you do decide to give them a small amount, ensure they are plain, unsalted, and chopped into small pieces to minimize choking risk.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
