Cats love milk but can sometimes have problems digesting ordinary cows' milk. The lactose in ordinary cows' milk can cause digestive problems, that's why we make our yummy Milk for Cats from lactose reduced cows' milk. Reducing the lactose means it's easy to digest while retaining all the natural goodness of milk. Cats love our delicious milk and it also helps keep them hydrated, especially in the warmer months.
