So, the other day, I was at this guys house to clean his pool, and I see this chipmunk chilling about two feet from where I was going to be standing in a moment. Nothing out of the ordinary there, I am always seeing chipmunks. However, when I get really close to it, it just sits there. Which is rather out of the ordinary. Chipmunks are pretty skittish. So I go to shoo it away with my foot, and it just sits there. At this point I notice that it is missing a large patch of fur on its head, and the skin there is black, and though I can't see it well, the other side of its head appears to be the same. It was weird.
