Can cats eat cheese?
Only with care.
Cheese isn't toxic to cats, but it's not a great treat. Most adult cats can't digest lactose well, and cheese is salty and fatty. A pea-sized piece now and then is fine for most healthy cats, if it doesn't upset their stomach.
Are cats lactose intolerant?
Kittens make lactase, the enzyme that digests milk sugar, but most cats make much less after weaning. That's why dairy often causes diarrhea, vomiting, or gas in adult cats. Hard cheeses contain less lactose than milk, so some cats tolerate a tiny amount.
Which cheeses are safest?
- Better: small amounts of hard, mild cheese like cheddar or Swiss, which are lower in lactose
- Avoid: soft and fresh cheeses like cream cheese and brie, which have more lactose
- Avoid: cheese with garlic, onion, chives, or herbs, which are toxic to cats
- Avoid: blue and moldy cheeses
How much cheese can a cat have?
No more than a pea-sized piece, and not every day. Cats need very few calories, so even a small cube of cheese is a big treat for them. Our cat calorie calculator shows your cat's daily treat budget (about 10 percent of calories).
Skip cheese entirely for cats with kidney disease, heart disease, weight problems, or a sensitive stomach, unless your vet says otherwise.

Frequently asked questions
Can cats drink milk?
Most adult cats shouldn't. Cow's milk often causes diarrhea and stomach upset because cats can't digest the lactose well. Water is all they need. Special lactose-free cat milk is available as an occasional treat.
Can kittens eat cheese?
It's best not to. Kittens need their growth diet, and dairy can upset their stomachs.
Can I use cheese to give my cat a pill?
A tiny piece can work, but ask your vet first: some medicines shouldn't be taken with dairy. Pill pockets made for cats are another option.
