I gave her a careful check as soon as I read this, can't believe I didn't think of mites. I didn't find anything, though, her scales are perfect and her eyes/mouth/butt are all clear. I use a combo of newspaper and paper towels as her "substrate," the only thing in her tub I could imagine having a higher risk of mites would be her stick and bark hide, but I checked those out too. Do you think it's still a possibility enough I should get her a vet appointment?
