Like I said, we aren't SEEING the enclosure. Quote- " She's in a wooden viv with a CHE (with a lamp cage) set up to a thermostat."
Is the CHE/cage inside the enclosure? You also mentioned climbing branches- could she be scraping the (hot) cage around the CHE?
It would sure help if snakes could talk...until then, we have to play "detective" to figure out what the heck they did.
I don’t get it cause I use the same type of enclosure and the guard it self once the temperature is up never gets above 35 ish. So without seeing the enclosure I can’t advise any more either
