"I was thinking mangy possum."
The ears are all wrong for any known wild creature indigenous to the North American continent. That is no known species, and I have now seen 4 different instances where that animal has been found and photographed dead.
No 'coon, wolverine, fisher cat, pine martin or 'possum. No mangy coyote, porcupine or Eastern Red wolf.
That is a newbie.
