So i have this cat that just gave birth to 6 kittens 4 days ago, and when she gave birth an hour after she started eating her kittens! She tried to eat all of them but i saved one. Ive decided to care for him myself. Things have been going good until I noticed he was cold so I introduced this heat pad. Now he's gone from crying evey 2 or so hours for food to almost never crying for food, just when the heat goes out. what do i do. He seems super tired all day now. Have i done something wrong. Please help!
