Same, both my red tail boa and my bp shed in their hides and usually lay on it or my red tail boa will poop on it and then sit on the warm side of her cage till I open the door and see a ball of shed with a giant poop winking at me from inside her cat box hide. Of course another tell tale sign is when I open the door and she comes darting out trying to climb on my arm and shoulder as if saying "omg you left me in here with a poop for hours!!!"
