Safe in small pieces, raw or cooked. Too much causes gas.
Short answer
Yes, it's safe for cats to have a small piece of raw cauliflower. It's best to cut it into tiny, manageable pieces to prevent choking. Eating too much can lead to gas or an upset stomach. Offer it plain, watch for any signs of discomfort, and call your own vet if anything seems off.
