You can keep the log. What I used to do before Hissy outgrew her half log, I used it as something that she could use to "safely" get from one hide to the next. But relying on it as your sole hide is just not going to work. As others have already said, grab a couple of clay pot saucers (not the pot itself, the saucer that it sits in) and you will have a much more relaxed and appreciative snake. (OK, snakes don't really appreciate stuff, but I like to personify them cuz it makes ME feel better)

Edit: If you hit up a home depot or Lowes or something, you can often find some saucers that already have a small chip in them or something that you can get for really cheap.
