Nuts are high in fat, which can upset your cat’s digestive system, causing vomiting, diarrhea, and even pancreatitis.
Some nuts, such as macadamia nuts, are poisonous to cats.
Almonds, pecans, walnuts, and peanuts can also cause gastrointestinal issues and pose a choking hazard.
Suggestions
It's best to avoid feeding nuts to your cat.
Instead, consider offering small amounts of plain, cooked chicken, turkey, or white fish as a treat.
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.
