Yes, a small piece occasionally is safe — expect gas, possibly loud.
Why it’s fine
Brussels sprouts are non-toxic and fiber-rich, but they are among the most gas-producing vegetables for any gut, including a cat’s small one. Plain and rare, they are harmless; the bacon fat and butter humans pair them with are not.
How to serve it safely
Offer a small plain piece, boiled or steamed, occasionally. Skip anything roasted with oil, salt or bacon.
When to call the vet
Call your vet only if bloating seems painful or vomiting repeats.
Common questions
Why does one sprout cause so much smell?
