My foster cat had a litter of 5 healthy, beautiful kittens 3 days ago. I think I have a few weeks before I have to start worrying about it, but what do you folks usually do when the kittens are big enough to get out of the nesting box? Mother and kittens are currently in their nesting box in their own warm, carpeted basement room, and it's pretty empty, but there is a couch and small table, as well as a built-in bookcase with some various items stored in it. I might flip the couch over onto it's back so there's no space for kittens to get underneath it. Should I just get a larger box to confine them at night when I sleep to keep them out of trouble? I've had kittens before, but only one at a time. I usually confine them to a bathroom with food, water, litterbox and toys when I can't watch them so they don't get lost somewhere in the house. I also have a mesh sided baby playpen, which I'll probably use when they're supervised, but I don't want to risk them getting their claws caught in the mesh when I'm not close. Tips?
