Yeah it's definitely way too big for him... He's 9 months old and 383 grams last I weighed him.

Sorry, I'm probably panicking a bit. It's just from watching him grow it's apparent how soon it'll be that he'll start to get cramped where he is now. I've been saving his shed skins and from his first shed here to the third one he just sloughed off today he's about doubled in size. I get that I have more time than I realize given it's a BP (he's as textbook as they come and barely moves 99% of the time), but I'm nonetheless antsy about finding a solution for his permanent adult home.
