⚠️ Quick Answer: Small Amounts of Hard Cheese — But Most Cats Are Lactose Intolerant
Despite the cultural image of cats enjoying a saucer of milk, most adult cats are lactose intolerant. A tiny piece of hard cheese like cheddar is usually tolerated, but dairy in general can cause diarrhoea, vomiting, and stomach pain. Cheese is not nutritionally necessary for cats.

| Toxic? | Not toxic, but poorly tolerated |
| Lactose Intolerant? | ~90% of adult cats lack sufficient lactase |
| If Any | Tiny piece of hard cheddar — max pea-sized |
| Avoid | Soft cheese, blue cheese, cream cheese, milk, cream |
Why Cats and Dairy Don’t Mix
Kittens produce lactase to digest their mother’s milk, but as they wean, most cats lose up to 90% of their lactase production. This means undigested lactose ferments in the gut, causing gas, bloating, diarrhoea, and discomfort.
Cats are also obligate carnivores — their digestive system is designed for meat, not dairy. Cheese provides no essential nutrients that a cat can’t get from a proper cat food diet.
Using Cheese to Give Cats Medication
One practical use for cheese is hiding pills. A pea-sized piece of soft cheese wrapped around a tablet can make medication time much easier. If your cat tolerates cheese well, this is an acceptable occasional use — but ask your vet whether dairy interacts with the specific medication.
Safer Alternatives to Cheese
- Cooked chicken — small shredded pieces (unseasoned)
- Cat-specific treats — Dreamies, Webbox, Lick-e-Lix
- Lactose-free cat milk — Whiskas or GimCat brands
- Cooked fish — plain white fish or tinned tuna (in moderation)
Frequently Asked Questions
Why does my cat love cheese if it’s bad for them?
Cats are attracted to the fat and protein content of cheese, not the lactose. The high-fat aroma is irresistible to many cats. Unfortunately, just because they want it doesn’t mean their digestive system can handle it.
Can kittens eat cheese?
Kittens tolerate lactose slightly better than adults, but cheese is still not recommended. Kittens need a carefully balanced diet to support rapid growth — stick to kitten-specific food.
Is vegan cheese safe for cats?
While vegan cheese avoids the lactose issue, it often contains garlic powder, onion flavouring, or artificial additives that are toxic to cats. It’s best avoided entirely.
