Normal for BPs to be active at night, & hiding by day. "Stressed" would be active during the day.Some demolish their furnishings more than others, that's life.
Hiding more than usual means he's not looking for food, which means yes, he's probably going into shed cycle. If you're worried, you can "peek"- & have a small flashlight in hand to shine on his eyes if you want to be really certain, since sometimes the "cloudiness" is hard to see otherwise. I wouldn't worry... Snakes "know" (feel) a shed coming before we can see the evidence.![]()
