Can Cats Eat Peanut Butter?

Yes, in small amounts — the ASPCA names peanut butter among the foods you can safely share with your pet, provided treats stay under five percent of the day’s calories.

What the ASPCA publishes

Peanut Butter appears on the ASPCA’s “Sharing is Caring” list, which says:

Many pets love peanut butter.

The same page sets a limit that travels with that sentence: snacks should be no more than five percent of your cat's daily calorie intake, because people food tends to be high in fat and sugar, and too much fat can inflame the pancreas.

Common questions

Yes, in small amounts — the ASPCA names peanut butter among the foods you can safely share with your pet, provided treats stay under five percent of the day’s calories.

How much peanut butter can a cat have?

The ASPCA does not publish a quantity for peanut butter specifically. It publishes a limit for treats in general: snacks should be no more than five percent of your cat's daily calorie intake, because people food tends to be high in fat and sugar and too much fat can inflame the pancreas. We give you their limit rather than inventing a portion for this food.
