A teaspoon of plain cooked black beans is fine, but beans are no food for a carnivore.

Why it’s a sometimes-food

Cooked black beans are non-toxic and provide fiber and plant protein, but cats are obligate carnivores and get little from legumes. Undercooked or raw beans contain lectins that irritate the gut, and canned versions carry salt and seasonings.

How to serve it safely

Offer a teaspoon of plain, thoroughly cooked, unsalted beans occasionally, mashed if your cat seems interested.

Warning signs to watch for

Gas, bloating and loose stools after larger servings; canned beans in salty liquid can cause vomiting and thirst.

When to call the vet

Call your vet if diarrhea lasts more than a day after eating beans or any new food.

Common questions

Are beans good for weight loss in cats?

No. Cats lose weight on portion-controlled high-protein diets — ask your vet for a plan rather than substituting plant foods.
