Can Cats Drink Milk?

Lactose intolerance

Most cats are lactose intolerant, meaning they cannot digest the lactose sugar found in milk. This can cause digestive problems such as vomiting, diarrhea, and gas.

Stomach upset

Even cats who are not lactose intolerant can still experience stomach upset after drinking milk.

Weight gain

Milk is high in calories, so giving it to your cat can lead to weight gain. This is especially true if your cat is already overweight or obese.

Milk allergies

A small number of cats are allergic to milk. This can cause symptoms such as itching, hives, and swelling.

Other risks

Milk can also contain bacteria that can make your cat sick. This is especially true if the milk is not pasteurized.

Drinks milk

If your cat drinks milk, it is important to monitor them for any signs of digestive problems. If you see any signs of problems, take your cat to the vet immediately.


There are a number of alternatives to milk that you can give your cat. These include lactose-free milk, goat's milk, and cat milk formulas.
