Cats can eat cheese, but only in very small amounts and infrequently. Many cats are lactose intolerant, meaning they lack the enzymes to properly digest dairy, which can cause digestive upset such as vomiting, diarrhea, gas, or constipation. Cheese is not toxic to cats but is high in fat and salt, which can lead to health issues like obesity and salt toxicity if given in excess. Some cheeses are safer than others; plain, firm cheeses like cheddar, parmesan, Swiss, and gouda are better choices, while soft, high-lactose cheeses like cream cheese, cottage cheese, and mozzarella should be avoided. Cheese-flavored cat treats made specifically for cats are generally safe in moderation. Overall, cheese should be an occasional treat and not a regular part of a cat's diet.
