I have a few BPs (maybe 2-3 out of 15) who don't use their hides, and the corns are rarely in theirs! Dave and Nerissa the BPs never use them, and their husbandry/rack is basically perfect. I still leave one in Dave's tub, since he will use it from time to time... but I removed Nerissa's, as she'd just knock it over or sit on top. She is perfectly happy under the newspaper, or simply curled up in the corner - so I guess some snakes don't care for man-made hides? :oops:
