I think I must be living in the Wild Kingdom this Winter. Have a gray fox visiting me and leaving his calling card nightly. This is making my dogs crazy. Didn't know they could jump fences, but apparently they even climb trees and sometimes sleep in them to stay out of the coyotes reach. Finally spotted the little fellow yesterday just before dusk. He was too fast for me to get a shot with my camera. But here is a photo of a similar one.
