Short answer

A small amount is fine, but half a cup is already a lot for a 10-pound cat. Stick to a tablespoon or two of chopped, plain cauliflower as an occasional treat. Too much will cause gas and an upset stomach. Offer it plain, watch for vomiting, and call your own vet if anything seems off.

Cauliflower — Food safety facts

Safe in small pieces, raw or cooked. Too much causes gas.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Cauliflower is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
