I adore my backyard fox. She's done a fantastic job at getting rid of mice and chipmunks. She doesn't seem to go after the squirrels as much, but that could be because my squirrels are the size of cats and have no fear. I also have a resident opossum in the trees. Not sure if it's a boy or girl, but that little one is often around cleaning up apples that fell from trees or tomatoes that had fallen from the ground.
