!! i just realized that the drawer carts would be perfect for my mouse/rat breeding project!!
the only thing i'd have to do to them is drill holes in the front & sides of the drawers for ventilation & water bottle access.
i will keep the feeder mice in the 2 drawer cart & use a 3 drawer cart for breeding...its perfect (and it more space efficient then stacking large storage bins).
It's really not that perfect, and any holes that you drill will give the mice purchase to chew their way out. The drawers themselves are also rather loose at the top, another means of escape.
