cats

Hi all! I was hoping someone could give me some advice! I have a new momma and six squirts, five days old. I made her a birthing box and she liked it for a bit, but now she keeps moving the kittens to a place under the bed where it’s kinda dusty and feels like a bad place for babies. I would move them back to the box and five minutes later she would move them back! The box is some clean towels on top of a pillow. I don’t want to stress her out, but I think they would be better back in the box. Anybody have some advice?
