I owned one for a while and used it as a cheap dresser. Fell apart within a month. I wouldn't house any animal in one of these. There are plenty of blueprints int he DIY section that are cheap to produce, you just have to be willing to put in a little effort into construction. The simplest thing you could do is buy a metal shelving system, line heat tape along the back of the shelves and buy tubs that will fit on the shelf with locking tops, drilling holes for air.
