Hey yall. I've been reading this site here and there over the last three years and it's been very helpful in raising my baby. This time however, I'm not sure what to do with him. He recently started chewing his fur out and while this has happened before from time to time, it's never been this bad. He's a primarily inside squirrel, though we do have a cage outside that we'll sit in. He's an only squirrel. His diet consists of fruits, veggies, nuts, and pinecones I find in the yard. He acts normal for him, other than biting at himself so badly. Is it mange? Should I treat? I have a picture but I'm not sure how to post it
