Just got my pastave today and he is making himself at home.. I currently have 2 hides.. 1 on the hot side and 1 on the cool side.. I have read on here that they need to be the same size but mine aren't at all.. He spent most of his first day in the hot hide, but I just noticed him out and about and he crawled into the cold hide and is currently just chilling out in there.. He doesn't seem to mind at all.. Should I just leave it the way it is or should I make the hides the same size?
