Forgive my chuckling........
i don't blame you for being creeped out.
i grew up in the woods, on 8 acres of land, at my parents house. i am totally comfortable with wildlife, but not in a suburban environment and not up against my front door. in my experience, wildlife, too comfortable being close to humans, smacks of rabies. and i told the guy at animal control that the mangy one reminded me of the hyenas in the Lion King.
