Well, we're in the process of moving, I'm contemplating making an appointment at the reptile vet out in the desert (where I'm moving in two weeks) she never sits with her mouth open. She is coming up on shedding time. Last shed was before valentine's day I believe (of course, I have a shed journal that's lost in my room) she isn't blue. But I've noticed her scales have kind of a blue sheen before she'd, and her scales certainly have that sheen. The vet out here is kind of a moron, but if she had a free appointment I'd rather have a professional opinion on it.
