Wiggles has two hides made out of foam sheet. His warm hide lies flat with the opening at the front. It sits under his RHP and the top serves as his basking spot (post #293). His other foam hide I keep on the cool side and this one I stood up on the back end with the opening at the top. I thought he might like this option because he likes to wedge himself between books on my bookshelf, but I've never seen him use it, until tonight.
So, if you need to place a hide and you're short on floor space, consider putting your hide on the side of the enclosure. Wiggles likes it. Maybe, your snake will too.
