Is oatmeal safe for cats?

Oatmeal is cooked rolled or ground oats. Plain, cooked oatmeal is not toxic to cats, but it has little value for a meat-eating animal. Cats are obligate carnivores, so they get what they need from meat and never need oatmeal. If you offer it at all, treat it as a rare, tiny extra.

How to serve oatmeal to your cat

What to avoid

How much oatmeal can my cat have?

Offer just a tiny taste, about a fingernail-sized piece, once in a while. Treats, including oatmeal, should stay under about 10% of your cat's daily calories.

Signs your cat may be having a problem

Watch for vomiting, diarrhea, drooling, pawing at the mouth, loss of appetite, tiredness, a swollen or painful belly, or trouble breathing. Contact your vet right away if you see these signs, or if your cat has eaten any of the parts listed above.

Emergency? Call your vet or an animal poison hotline straight away: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661 (US numbers, a consultation fee may apply).

Frequently asked questions

Can kittens eat oatmeal?

Young animals have more sensitive digestive systems and a carefully balanced diet, so check with your vet before adding oatmeal. If you get the go-ahead, start with an even smaller amount than an adult would get.

What if my cat ate too much oatmeal?

The most common result is an upset stomach with vomiting or diarrhea. Offer water, skip further treats, and call your vet if symptoms are severe or last more than a day, or if your cat ate any of the parts listed under "What to avoid".

How often can my cat have oatmeal?

Treat it as an occasional extra rather than a daily food. Once or twice a week at most is a sensible starting point for a healthy adult cat, and less for small ones.
