They aren't completely gone, but some are pretty close. I think most or all should grow back, but I wish I knew how it happened so that I can make sure it doesn't happen again. it looks pretty painful.

If they had fallen out then I would suspect an infection or diet deficiency, but they appear to be broken off. If she didn't get such a varied diet I might still suspect a dietary deficiency making them brittle, but she does have a diverse diet including Reptomin. Maybe she was reared up too rapidly prior to my getting her and the tissue isn't very dense, thus prone to breakage?
