I keep my two pairs in 3" deep aspen bedding and a 6" water bowl and cage size requirements are as follows ...the cage perimeter should be one and a half times the length of the longest snake in the cage, the hight should be tall enough to accomadate a screen or vent 8"x12" on each end to ensure proper ventalation (coachwhips/racers spend more time above ground than under ground like most other snakes)the moving air keeps their wild sences going and wildcought individuals will undoubtably require these cage specs to assure survival. as for humidity...I mist my animals only as their going into shed and do so under their hidbox so I don't recommend misting entire cage but just under the box, I never have a eyecap problem or any stuck sheds. also I have found that if your cage faces a window or glass door you'll see them out more often and the wild snakes will remain sein longer, new snake? it should eat mice but you can't hold most coachwhips like pets,they'll never tame but will breed if you leave them alone.
