Can Cats Eat Cheese?

Why are cats lactose intolerant?

Kittens produce plenty of lactase, the enzyme that breaks down lactose (milk sugar), because they need it to digest their mother's milk. As cats mature past weaning age, lactase production decreases significantly. By adulthood, most cats produce very little lactase, which means dairy products pass through their digestive system undigested, causing gas, bloating, diarrhea, and stomach discomfort. Research suggests that 50% to 75% of adult cats have some degree of lactose intolerance.

Is a small amount okay?

A tiny piece of cheese as an occasional treat is unlikely to cause a problem for most cats. Some cat owners use small bits of cheese to hide medication (similar to pill pockets). The key is quantity: a pinch-sized piece every now and then is very different from a regular serving. If your cat has never had cheese before, start with a very small amount and watch for any digestive reaction in the following 12 to 24 hours.

Which cheeses are better?

Hard, aged cheeses like cheddar, Swiss, Parmesan, and Gouda contain less lactose because the aging process breaks much of it down. These are generally better tolerated than soft cheeses like brie, cream cheese, or cottage cheese, which retain more lactose. Avoid any cheese that contains added herbs, garlic, or chives (common in flavored cream cheeses and herb-crusted varieties), as the Allium ingredients are toxic to cats.

Are there better treat alternatives?

If you want to give your cat a special treat, small pieces of plain cooked chicken, turkey, or fish are nutritionally better choices that won't trigger lactose-related digestive issues. Commercial cat treats are formulated for feline digestion and are the safest option overall. Cheese works in a pinch for hiding pills, but it shouldn't be a go-to treat for cats with sensitive stomachs.
