Cheese is not a natural part of a cat's diet. Cats are obligate carnivores, which means they can only get necessary nutrients from meat. But even though cheese is also high in protein, it can upset a cat's delicate digestive system. The reason for this is that cats don't tolerate dairy very well.
Can cats eat cheese? According to experts, yes — but only in moderation. If you give your cat cheese at all, just give them a small piece once in a while, about the size of a dice. For example, you might opt to limit your kitty's cheese intake to times when you need to hide a pill for them.
Why is cheese bad for cats? Most cats can't digest dairy products which means eating milk, cream or cheese could quickly lead to digestive issues such as diarrhoea, constipation or vomiting. The explanation has to do with how the feline digestive system evolved.
