We have its litter food and even a nesting box inside a large dog cage, my grandpas house, he didn't want her running all over the house with kittens hanging halfway out lol
She normally free roams the house though. She's only been in there since probably the day I took her to the vet and got the X-rays. As soon as the kittens get a little bigger well let them all out. Probably in a couple of weeks or so.
