My cat gave birth to 4 beautiful kittens. After giving birth she moved her kittens to my closet as its dark and quiet and has been feeding her kittens. Its been almost 18 hrs and she hasnt eaten much. she drank milk but very small amount. I'm bit worried. Is it normal? Moreover she didnt leave her kittens at all. She hasn't even gone to poop or anything. I seriously dont know what to do
