Yes, in small amounts. Plain cooked broccoli is non-toxic to cats and safe as an occasional veggie treat. Steaming softens it and makes it easier to digest; large amounts can cause gas, so keep the portion small and skip butter and seasoning.

Why this answer
Broccoli contains no feline toxin and provides fiber and antioxidants that pass harmlessly in small amounts, though as a cruciferous vegetable it can produce gas and loose stool if a cat eats a lot. It offers an obligate carnivore little nutrition, so it belongs in the occasional-treat category, cooked and plain.
Watch for
Gas or bloating from the fiber
Loose stool if a cat eats a large serving
How much is okay
One or two small cooked florets or bite-sized pieces, once or twice a week, plain and unseasoned.
Serve it safely
Steam or boil until soft, with no salt, oil, garlic, or cheese sauce.
Cut into small pieces and let it cool before serving.
Offer a tiny amount first to see how your cat's stomach handles it.

Feeding Your Cat

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.
