Don't I know it. They were 3 weeks old and on the bottle...Now they are 5 weeks old. It's nothing like fostering a turtle...these kittens are so much fun and so responsive. The big cats are afraid of the babies...lol but Simon is surprisingly getting interested in playing with them. He's declawed, but he takes those big paws and smacks a baby and sends it rolling like a bowling ballFostering a whole litter? Gonna be hard to give them back when the time comes.
