Paw prints

I woke up this morning to the first real snow fall of the year. I was taking pictures of it from the second floor window and I noticed paw prints in the snow going up the walk-way stairs in my back yard and circling the pond. The snow fell last night and there were no human prints around these. They look too big to be a cats, although that can be deceiving, they weren't very clear and foot prints can grow causing big foot evidence and the like. I don't think they are a dog's prints because dogs aren't usually that subtitle, there would be a whole mess of prints running back and forth. I've decided they must be from the fox, might as well believe that. If you look close you can see a paw print right at the upper edge of the wedge of the upper pool.
