While you may get cat claw marks in the right soil conditions the claws look too long to be cat claws. I always thought they would be some marks, but with not appreciable length to them until extended. If I were putting my dogs on it I'd think I was running a coyote. Though if it's as big as you indicated, I'd be moving on because I'd be thinking it's a dog of some sort. The needles I see to the left and upper right (i think that's where they are in the photo) sorta give an idication as to size and I would say coyote. Of course I've walked a dog track back to someone's house on an occassion or two hoping it was a big coyote, wondering if it was really a colder track than I thought and why the dogs weren't ready to open up on it.
