What type of animal produces a commonly found milk that is easily digested by felis catus (otherwise known as the common house cat)?

Question

NEVER give a cat cow milk or cow's milk products! They cannot properly digest the high levels of lactose (lactose intolerance). Feeding cow's milk to cats will lead to diarrhea, horrible flatulence, dehydration, and malnutrition.

Answer 1

Never give a cat cow's milk or dairy products as they do not digest it properly.

Answer 2

This may shock you, but the best milk for a cat is... cat's milk.

Otherwise, the only liquid that a cat really needs is water.
