Can Cats Eat Cauliflower?
By Pettings · Sources checked Nov 2, 2026
Cats can eat small amounts of plain cooked cauliflower. Tufts Petfoodology lists boiled cauliflower, drained and without salt, among its low-calorie treats for dogs and cats. Most cats show little interest in it, and that is no loss.
What Cauliflower Offers a Cat
Cauliflower is mostly water, with some fiber and small amounts of vitamins and minerals. The Cornell Feline Health Center explains that cats are obligate carnivores that rely on nutrients found in animal products. A complete cat food already covers those, so cauliflower is a very low-calorie extra with no special benefit for a cat.
Its fiber can add a bit of bulk, but Tufts Petfoodology notes that the fiber in vegetables is variable and typically low. Cauliflower should not be used to treat constipation or diarrhea without a vet's advice.
How Much Cauliflower Can a Cat Have?
WSAVA advises keeping treats under 10% of daily calories, or about 22 to 25 calories a day for a 10-pound adult cat. Tufts lists a half cup of boiled cauliflower at 15 calories, so 1 to 2 tablespoons comes to only about 2 to 4 calories. That fits the allowance easily, and it should still count as part of the day's food rather than an extra.
Begin with a couple of small pieces. Cauliflower can cause gas in some animals, and a cat that eats a lot of any new vegetable may get loose stool. Kittens, seniors, and cats with diabetes, kidney disease, urinary stones, pancreatitis, or food allergies should have treats chosen with their veterinarian.
How to Serve It
Boil or steam the florets until they are soft enough to mash with a fork. Let them cool, then chop them into pea-sized bits or mash them into a little of your cat's regular food. Raw cauliflower is hard and crunchy, so cooked is easier for a cat to chew.
Serve it plain. Skip cauliflower with cheese sauce, butter, salt, or roasted spice blends, and leave out cauliflower rice dishes and mashed cauliflower made with garlic. The ASPCA lists garlic, onion, and chives as able to damage a cat's red blood cells, and garlic is common in cauliflower recipes. Frozen cauliflower is fine once cooked, as long as no sauce or seasoning came with it.
If your cat has a medical condition or eats a special diet, talk to your veterinarian before adding cauliflower.
Common Questions
Can cats eat raw cauliflower?
Cats can lick or chew a little raw cauliflower, but cooked is the better choice. Raw florets are firm and harder for a cat to break into small pieces. Tufts Petfoodology lists cauliflower as a treat when it is boiled, drained, and unsalted. Steam or boil it until soft, cool it, and chop it into pea-sized bits before offering any.
Can cats eat cauliflower rice?
Plain cooked cauliflower rice is fine for cats in small amounts. It is the same vegetable, just chopped finely, so a teaspoon or two mixed into food is easy to eat. Many store-bought and restaurant versions add garlic, onion, oil, or salt. The ASPCA lists garlic and onion as able to damage a cat's red blood cells, so only offer the plain kind.
Is cauliflower good for cats with diarrhea?
No, cauliflower is not a treatment for diarrhea in cats. It contains some fiber, but Tufts Petfoodology notes that vegetable fiber is variable and typically low, and new foods can sometimes make loose stool worse. A cat with diarrhea that lasts more than a day, or that comes with vomiting or low energy, should see a veterinarian rather than get home remedies.
Can kittens eat cauliflower?
Kittens can try a tiny piece of plain, soft cooked cauliflower, but they do not need it. A kitten's calories should come from complete kitten food to support growth. If you offer some, keep it to one or two mashed pea-sized pieces and watch for gas or loose stool. Ask your veterinarian first if the kitten has a sensitive stomach.
Can cats eat cauliflower every day?
A spoonful of plain cooked cauliflower a day is low in calories and unlikely to harm most adult cats, but it adds nothing they need. Tufts lists a half cup at just 15 calories, so a tablespoon fits easily under WSAVA's treat limit. Some cats get gas or soft stool from extra fiber, so cut back if that happens.
