I adopted a mother and daughter, judy and liza about 3 weeks ago. They are divided from my boars with a few grids, and have been for a week. Today I just noticed the Liza's face right above her nose looked funny when I was about to do floor time. The fur is gone and it looks very rough and cracked, and like it may have bled at some point. Mom looks fine. I've never seen anything like this and I'm very worried. Should I try to clean it? Leave it alone? Is it contagious?? Help! This is the best photo I could get!
