Does it mean anything when a snake burrows? I just got some new bedding for my snake (a mix of coconut husks and bark-cypress I think) and for the first time EVER, as soon as I put her in (after cleaning her cage), she starts burrowning under the new bedding..

I've heard of snakes doing this, but mine never has. I'm only concerned if it means something like she's really stressed out or something.

Please comment, and thanks in advance for your help!
