Can Cats Eat Brussels Sprouts?

Safe in small amounts — Brussels Sprouts for cats.

Safe in small amounts

Why: Plain cooked Brussels sprouts are not toxic to cats. They are famous for causing gas, so a tiny amount is plenty — and raw sprouts are hard to digest.

Safe serving: Half a small sprout, plain and cooked, as a rare treat.

If your cat ate brussels sprouts: No action needed for plain cooked sprouts. Expect gas.
