Adam,
Maybe I'm losing my mind then, because I swear I remember you telling me that one time when I first started. I think in a question I asked about acclimation. I'll have to go back and look.
I "thought" you said that them constantly roaming and climbing the walls was an indication of stress and that they were looking for ways of escape due to that stress.
Ah well, what's a snake mommy to do? Relax, right? LOL
