A kitten should drink about 1/2 to 3/4 of an ounce (13 to 18 ml) every 20 minutes. He will learn how much he needs by watching you or his mother, but he can’t tell you exactly how much he needs because it depends on the temperature and humidity in the room.
How do I know if my cat is drinking enough?
If your cat doesn’t drink enough water, his eyes may appear glazed over, and they’ll feel very dry. His tongue might be sticking out between his teeth when he drinks – which means that not enough water is being swallowed. If your pet doesn’t seem thirsty at all, don’t worry; just assume that she’s getting enough moisture from her food so she isn’t dehydrated . Cats love wet food! The only exception would be a sickly kitten who has lost too much body weight during illness or stress , for example by not eating as much as normal due to illness or stress within the household.
