plastic tubs hold humdity the best. a small under heat pad works well to add gradual heat set at 78 and that gives me 80% humidity in my tubs..the more differnt feeders the better, feed daily till 8 months then twice aweek ,at 18 months feed once a month..sometimes they eat normally sometimes they skip a day or two..i feed mine crickets,worms and fish.im not going to feed mice untill 8 months or so.cuz their very high in fat .that is basic pacman set up ,u can add a plastic leaf or two to help them feel safe
