Hello, I'm new here. I've known this grey wild squirrel for almost a year but hadn't seen it for about 3 weeks until it shown up the other day when I noticed something happened to it's ear. It seems over the past few days whatever is going around its ear has gotten worst and I don't know if its some sort of infection or injury. The ear is missing now and is also missing a patch of fur on its back end. If anyone can help me understand what may be going on from the pics I've attached, it would be greatly appreciated. Thank you.
