I use them too. I know for a fact that my snakes can fit all the way in them if they want so if they decide they want to wear it like a shell or sprawl out from under it, fine. I kind of look at it like kicking the blankets around on the bed. Or, on those cold, winter nights when I get a little warm and toasty under the blanket and I kick out my leg to cool off a bit...
