I did somelooking on web sites about cat tracks. One of the biggest clues to cat tracks are the toes are not even. They are sort of like your hands where some of your fingers are longer than others. One of the cats toes are further forward than the others. Claws sometimes are not visible except in certain conditions. Thisis a track that I found in the river bottoms an have seen it around several times. Ithink it is a cat track due to the forward postion of the toe. That phone is about 4.5" long for comparison.
