Guinea pig eating its own hair! What is it?
She is eating it off the sides of her abdomen. She has never even seen a male, so she is not pregnant. It has been going on for a couple of months or more. We have tried covering her cage to give her more security, and have a pouch in her cage to crawl into. Nothing seems to help. We have been feeding her dry hay thinking it might be a protein deficiency, but to no avail. Uggh.
