Yeah! I made sure to "up" the three shedders' humidity, misted their cages down and put the usual plastic over their screen lids. I also make sure to spray insode of their hides too, because they seem to hide even more at shed-time.
But I actually caught my boa drinking water last night; not something I see often. He must have drank for at least 5 minutes, then just put his head back into his hide and slept (or meditated, or whatever it is they do in their hides, lol.)
