Two years ago I found only the front leg left of a grey fox in my trap, coyotes obviously had done this as their tracks were present and a bitch yote was in the trap 20 yards away. Later that same season I caught a grey fox that upon skinning I found he had been chomped around the back and in the ribs. Probably while he was in the trap as I had a coyote double 100 yards away. He must of put up a good fight for them to leave him alive.
