mine used to hid under its newspaper. I can see Del's point here if you been using it for a long time and it works for you then don't fix it. I learned when I was getting into this hobby (from another forum i'm on for herps) that a slight change in the enclosure can cause a snake to stress a bit and you should treat it like you did when you first got it. such as switching from news paper to aspen. she went off feed for a few weeks, I got tired of the aspen shavings falling all over my floor I switched back to newpaper and I had a ball that was eating again.

but the others had some good advice as well about why you should switch.
