Gray Fox spotted in my backyard

I was quite surprised to find a Gray Fox ( Urocyon cinereoargenteus ) in my backyard yesterday evening. At first glance I thought it was my neighbor's cat. When I casually called out with a sort of kissing noise, it turned and looked right through me. This curious creature was grayish-black with beautiful orange eyes.

After some searching, I discovered the gray foxes diet consists of small mammals, insects, fruits, acorns, birds, and eggs. They are excellent mousers and possess expert climbing skills. I started to wonder, if he was hungry enough, would he go after my cat?

Unfortunately, I did not get a picture. Has anyone else spotted a gray fox running around flanders?
