Missy has been trying to move her kittens for several days now. We decided to let her. She started with the runt and moved her into the box that they were originally in after they were born. After about 15 minutes we moved a second kitten in with her so she wouldn’t be lonely and had someone to cuddle with and keep warm. When we did, Missy immediately moved a third one into the box. After a while longer we moved the last two into the box with everyone else. We draped a small blanky over the box leaving about 4 inches open along one side. Now that the other cats have stopped “exploring” the box, Missy seems to be happy again.
