Hi all. I rescued a squirrel several weeks ago, and I noticed today she's lost fur on her cheeks. I read there are several different causes of this but I was hoping someone could help me determine what caused it? I don't think she has fleas and she has no visible mites, she rarely scratches. She was bathed when she came into the house. The skin seems healthy where furloss is occurring. I've provided a pic
