LOL I have one like that too stangs! Instead of moving from one hide to the other across the tub, she just moves herself and hide when she needs to thermoregulate. I've never been able to actually catch her at it (sneaky snake she is!) but it happens regularily. I check her in the morning and there's the two hides side by side either on the cool or warm side of the tub. Silly thing is they are absolutely identical. You'd think it would just be easier for her to just slither out of one and into the other but nope, she has to move hides to be a happy snake I guess.
I mean heck it's not like she cares about the caresheets! The whole "two identical hides, one on each side" doesn't impress her one bit apparently LOL.
