he doesn't necessarily need shelves..
Just turn that box down and cut part of the "roof" off! If it were a bigger box, it would be the same as having a shelf.
my feral is loose- cuz I got to trusting of her. So the stand off begins (again- she got loose this am when I emptied her cage due to severe water spillage...). Have to wait till she is in a place where I can scruff her and she has no escape. This am, it was the kitchen set up from Target. Now, who knows where she'll hide. In the meantime, she's having great kitten fun! Darn it!
