I've got one male and two females in each of the two larger Sterilite drawers pictured. The other 3 Sterilite drawers are currently uninhabited, but will be used for offspring and mother/father seperations post-breeding.

The water bottles I bought, while the smallest I could find, were still too tall to be hung on the sides of the drawers like normal, so I had to put them in at about a 30-degree angle. The top of the bottle being suspended by the wire that came with it (though custom-bent and cut), and the bottom of the bottle being supported by a zip-tie. It's working well, and the mice don't seem to climb on them too much. The only downside to the way they're placed is that water isn't being dispensed even with water still inside, as the angle prevents all the water from reaching the float-valve. No biggie, really.

I've also used a soldering iron to poke a series of holes along the sides, the back, and down the front of the drawers (you can't see them in one photo, because I hadn't finished at that time). I'm going to step up to rats as soon as Mr. Bojangles is ready for them, and for those I'll get a 20-long glass aquarium, and these Sterilite drawers will be for breeder Leo's and hatchlings.
