I've got this stump hide that my snake seems to really like. It has the open bottomed hole in the front and another hole in the back that is closed at the bottom. The other day he went out the back, got about half way out then tried going back in the same hole so a small loop of him was sticking out. I freaked and thought he was stuck so I pulled the stump out and actually he came out pretty easy. Just kinda scared me of him getting stuck and I've debated either cutting the bottom part of the hole out and smoothing the edges with a dremel or just sealing it up completely somehow.

I hate to totally get rid of it because it looks really cool and he seems to like perching on it as much as hiding in it. The top is open as well and he will crawl out the top and sit like this.
