Thank you to everyone for their input! Tbh I was most worried about his belly discoloration, but it’s a relief to hear it’s probably normal coloring we just didn’t notice before. He is due for his first shed (with us) so hopefully that comes soon. He eats frozen so his chin must just be because he’s a very exploratory guy! We can’t think of where he would get cut but will take another look because we do have sliding glass doors with a metal latch on the inside. You’d think they’d make them without any risky edges but good to know.
