I'm concerned with my guy too. He's popping and wheezing occasionally but I think it's possible it could just be because he's retained some skin on his head and around his nose. i've raised the humidity to 70-80 but he's not peeling. He is full grown. He's active when I take him out. He doesn't seem to be elevating his head any more than normal. Do you think I Should wait till his next shedding?
