She eats every time offered?
Poops? Urates? Good sheds??
i don’t see why you would change anything if your numbers are spot on...?
you don’t watch your snake 24/7 right ? She could be in there more than you even think or know.
When you take her out for some handling. Ease her into the warm hide. Show her it’s there. But I bet she knows it and uses it when she needs to.
Does she feel cold when you handle her??
my snakes are mostly in their cool hides
