Yes, in small amounts. Plain cooked cauliflower is non-toxic to cats and a fine occasional treat. Steaming makes it easier to digest, and because it is a cruciferous vegetable, a large serving can cause gas, so keep the portion small and skip butter and cheese sauce.

Why this answer
Cauliflower contains no feline toxin and offers fiber and some vitamins that are harmless in small cooked amounts, but as a cruciferous vegetable it can produce gas and loose stool if a cat eats a lot. It provides an obligate carnivore little nutrition, so it stays an occasional treat, best served plain and softened by cooking.
Watch for
Gas or bloating from the fiber
Soft stool after a larger serving
How much is okay
One or two small cooked florets or pieces, once or twice a week, plain and unseasoned.
Serve it safely
Steam or boil until soft, with no salt, oil, or sauce.
Cut into small pieces and cool before serving.
Offer a small amount first and watch for gas or upset.

Feeding Your Cat
Cornell Feline Health Center, Cornell University College of Veterinary Medicine — Feline nutrition fundamentals: cats are obligate carnivores; complete balanced cat food should be the diet base; treats should stay a small share of daily calories.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
