This is my solution for my small-scale mouse breeding. You can get these at Target or wal-mart for around $9. I drilled a lot of little air holes along the top of the sides and back, and one bigger one in front for the water bottle. The bottles are at an angle so you can open each drawer without interfering with the others. Each drawer holds between 1.2 and 1.4 mice, a "hiding hole", and a wheel. I know..."A wheel?" It keeps them happy, healthy, and gives them something to do other than trying to escape. The drawer on the lower left is being used to store food at the moment. Clean up is remarkably quick and easy. There are no edges or chewable corners on the insides of the drawers.
