Yes, plain cooked barley is safe in small amounts and even appears in cat foods.

Why it’s fine

Cooked barley is non-toxic and a common grain in commercial cat formulas, valued for its fiber and beta-glucans. As a treat it is nutritionally empty for a carnivore, and large servings just add bulk and cause gas.

How to serve it safely

Offer a teaspoon of plain, well-cooked pearl barley occasionally — no salt, butter or soup seasoning.

When to call the vet

Call your vet if a cat seems bloated or constipated after eating a large amount of any grain.

Common questions

What about barley grass or cat grass?

That is a different product — young grass shoots are safe and popular with cats, unlike the mature grain which is merely filler.
