Thanks!
Nope wasn't me. That snake stayed in the bag all the way home.
I keep my BP on regular newspaper, so I figured the RTB would be fine on a lil bit of flat newspaper with some shredded (because they like to burrow). I think it probably makes him a little more secure during the adaptation process. I'm going to slowly remove it and eventually put him on some aspen probably when I get the cage squared away.
