Peanut butter is not nutritionally necessary for cats and can cause digestive issues or allergic reactions.
It should be given only occasionally and in small amounts.
Suggestions
If you decide to give your cat peanut butter, monitor them for any signs of an allergic reaction such as itching, hives, swelling, or difficulty breathing.
Consult your veterinarian if any of these symptoms occur.
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.
