Tracks In the Snow ID

I notice on the deck amongst bird tracks, a paw print. No matter, cats cross my deck all the time. Then, looking out into the snow covered lawn, the paw prints are there as well, but not in a straight line of passing through. They are walking around on the snow. 

I haven’t seen any if the cats of that. 

Are those tracks a bobcat? Or just a big cat?  Photo is best I have so far.
