I have a fox den on a hill side about 300 yards from my house. I spotted it about a week ago. I have a spotting scope set up so I can watch them right through a sliding patio door. So far I have counted 7 pups at one time and I don't think there are any more than that. It's hard to count them when they are out because they are running around chasing each other, tumbling and rolling just like any other pups would do. They sure are cute. I don't have a camera capable of taking pictures that far and I don't want to risk disturbing them by setting up a trail camera.
