She is 1 and 1/2 years old, and we just adopted her from a shelter about 3 weeks ago. She seems extremely nervous, but has calmed down a great deal. I noticed a bald patch on her front leg, then I noticed the patch getting bigger over the span of a week and a half. Now I've noticed another bald patch on her belly. The skin isn't irritated, and I never see her biting or licking in those areas excessively. She also does not have fleas. I don't see clumps of her hair around either.
