I've had a total of five pet coons in my life. Two of them I kept for three years. They made good pets. 3 others I cut out of a tree at a young age, and kept them for a few months before taking them out to some big woods. They're very intelligent animals, very nosy too, as you saw there. Being far away from houses, I wouldn't worry about this unless it looked sick. I shot a sick one during deer season this year. Went back later and buried it. Don't know what it had, but it wasn't doing good. Cool post.
