I was thinking the same thing... Her humidity never dropped lower than 65%. Her last shed before I got her was a really bad one and the store I got her from didn't really do anything to try and help her after. She had stuck shed all over when I got her and there was one piece on her head that didn't come off until this shed. She also came with mites... I treated with PAM twice and they're all gone, but maybe her having mites had something to do with it? We'll see how her next one goes!
