Can cats eat cheese?
In small amounts as a rare treat, yes — but many cats tolerate the lactose in it badly. Hard cheese contains less lactose and is easier on them than fresh cheese.
Why cheese for cats?
Cats are obligate carnivores whose metabolism is built for animal protein. Cheese does provide protein, fat and calcium, but it is no natural part of a cat's diet and at best an occasional extra. The sticking point is lactose: most adult cats produce too little of the enzyme lactase to digest milk sugar. Long-ripened hard cheeses such as Parmesan, Gouda or mountain cheese contain considerably less lactose than fresh or soft cheese and are therefore often tolerated better.
How much is okay?
If at all, only tiny amounts: a pea-sized piece, at most once or twice a week. Cheese is very energy-dense and salty — larger amounts promote weight gain and strain the kidneys. For an average adult cat, cheese is a rare treat, not part of the daily ration.
How to feed it?
Best suited is a small piece of unseasoned, low-lactose hard cheese. Unsuitable are processed, fresh and soft cheeses (more lactose), heavily salted or seasoned varieties, cheese with onion, garlic or herb additives (toxic or irritating) and breaded or baked cheese. Offer cheese plain, never as part of seasoned dishes.
Risks & caution
The most common consequence is lactose intolerance with diarrhoea, flatulence or vomiting a few hours after eating. Add the high salt and fat content, which strains kidneys and weight. Cats with kidney disease, overweight, diabetes or a sensitive stomach should avoid cheese entirely. Cheese is also no substitute for high-quality cat food and must not crowd out the balanced diet.
Can kittens have cheese?
Kittens have particularly sensitive stomachs and need precisely balanced rearing food. Cheese is not suitable for young animals — even small amounts can trigger diarrhoea, which quickly becomes dangerous in kittens.
Signs of intolerance
After cheese, watch for diarrhoea, soft stools, flatulence, vomiting or a rumbling belly. Such signs point to lactose intolerance — skip cheese entirely in future. If diarrhoea or vomiting lasts longer than a day or listlessness sets in, see the vet, as diarrhoea leads to fluid loss.

Frequently asked questions
How often can cats eat cheese?
At most as a rare treat — a pea-sized piece once or twice a week. Daily cheese is not advisable because of lactose, salt and fat.
Which cheese is least harmful for cats?
Long-ripened, unseasoned hard cheese such as Parmesan or Gouda, because it contains hardly any lactose. Fresh and soft cheeses hold more lactose and are tolerated less well.
Can cats eat cream cheese or cottage cheese?
Only in tiny amounts and not regularly. Cream cheese contains more lactose than hard cheese, is often salted and can more easily trigger digestive trouble.
My cat loves cheese — is that a problem?
A small piece now and then is usually fine if the cat tolerates it. But do not confuse the preference with a need: cheese covers no nutritional requirement and should stay rare.
My cat has diarrhoea after cheese — what now?
That points to lactose intolerance. Skip cheese in future and provide fresh water. If the diarrhoea lasts more than a day or the cat seems weak, go to the vet.
Can kittens eat cheese?
No. Kittens have sensitive stomachs and need dedicated rearing food. Cheese can quickly cause diarrhoea in them.
