I use clay and corkbark hides, which she has used since the moment I put them in there. The clay hide is definitly warm to the touch all, it sits on the warm side under the heat lamp.

I also have the walmart heat pad that everyone here uses, I think that the bark doesn't dissipate heat quickly enough though, because I was having surface temps of almost 100 degrees.

Just out of curiosity, what would be a symtom of digestion issues?
