My BP has three hides. One cool end, one warm end and one in the middle. He favours the middle hide and completely ignores the other two. Since he's eating well, shedding well, pooing and weeing OK I think he knows best himself. I got a bigger hide for the warm end as he'd well and truly outgrown the smaller one (he moved and it moved too...suddenly I had a tortoise instead of a snake ). He went in it, had a good look at it, shot me a disdainful look and headed back for his favourite hide LOL.
