I got two little black foster kittens from the shelter today. They are my first fosters and are 4 weeks old. I can't get them to eat. They don't seem interested. I made a mush with dry food mixed with water and kitten formula. I also tried a bottle which they wouldn't take. Any other suggestions? Also the baby in the first picture is about half the size of the other and seems kind of skinny. She is still feisty though.
