Can cats eat cheese?
Last reviewed
Only hard cheese, once or twice a week.
Only a dice-sized piece of hard cheese, once or twice a week — that is how a cat can have cheese. Soft cheeses hold more lactose; most adult cats digest dairy poorly, and upset can show about eight to twelve hours later.
- How much
- A dice-sized piece of a hard cheese like cheddar or Swiss, once or twice a week at most.
- When it becomes a problem
- Digestive upset from dairy in a lactose-sensitive cat has been reported roughly eight to twelve hours after ingestion.
Treats count toward daily calories — the cat calorie calculator estimates the daily total.
How to give cheese safely
Offer only a dice-sized piece of a hard cheese occasionally (once or twice a week at most), and skip soft, high-lactose cheeses. Stop and consult a vet if diarrhea or vomiting follow, and avoid entirely if the cat has a known dairy sensitivity.
Signs that cheese is causing a problem
- Diarrhea
- Vomiting
- Reduced appetite or general digestive upset
Can cats eat cheese?
Only in a tiny hard-cheese bite, not as a regular treat. Cats can have cheese in that limited sense; cheese is high in fat and salt for a cat's size, and lactose intolerance is common once cats leave kittenhood.
Share cheddar, Swiss or Parmesan if you share anything at all; skip making cheese a daily snack.
Is cheese bad for cats?
Not in the toxic sense — unlike grapes and raisins or chocolate — but it is often a bad idea as a free snack. Lactose intolerance plus fat and salt relative to a cat's size are why this page is caution, not a green light.
If diarrhea or vomiting follow a share, stop and talk to a vet.
Is cheese OK for cats?
Only as an occasional dice-sized square of hard cheese, and no more than once or twice a week. Soft cheese is the worse choice on lactose; hard cheddar or Swiss is the lower-risk option when you share at all.
That "OK" still means tiny and rare — not a bowl of cheese.
How much cheese can a cat eat?
No more than a dice-sized square of hard cheese, and only once or twice a week. That portion is the PetMD limit for hard cheese — larger pieces raise the chance of an upset stomach.
Stop and call a vet if diarrhea or vomiting follow a share.
Is hard cheese safer than soft cheese for cats?
Yes, as the lower-lactose choice. Soft cheeses such as cottage cheese, cream cheese and brie often hold much more lactose than hard, aged kinds like cheddar or Swiss.
String cheese and cheddar still count as cheese treats under the same small-portion rule — they are not a free pass.
What happens if a cat eats too much cheese?
Digestive upset is the usual problem: diarrhea, vomiting, or a reduced appetite. In a lactose-sensitive cat, those signs have been reported about eight to twelve hours after dairy.
If your cat already has a known dairy sensitivity, skip cheese entirely.
Why does cheese upset some cats' stomachs?
Lactase production slows after weaning, so many adult cats cannot digest lactose well. Cheese adds fat and salt on top of that sugar load, which is why even a "safe" hard cheese stays a tiny, occasional bite.
