you are building tubs for them. put a little thought into it, cause they are chewers. I had aluminum water bottle holders and they chewed them. I now use the sterilite 58 qt tubs from walmart I cut the center out of the top and install 1/4 inch hardware cloth (screen). I cut a hole in the top hardware cloth to place a food feeder made out of 1/2 hardware cloth that goes to about 4 inches from bottom of tub. this gives room for the bedding and keeps the food dry. I keep the water bottles on the outside of the tub and drill a hole for it to go thru. I put 1/4 harware screen on both side of the tub where the bottle goes thru so they can't chew it. I had them in these tubs for little over a year now with no problems. one good thing is they do smell, but no where near as bad as mice or rats.
