They are all the same. All these tracks were right in a line on the path the sow took to water.
The picture tells the story.
Notice the soil was mud when the track was made. That throws everything off some.
In the first pic, notice the claw marks are nearly perfect circles. This is because cat claws curve down when extended. Looking at the track in person you could see how the claws traveled down into the mud instead of toward the path of travel like a canid. Also, when walking in mud, cats will extend their claws leaving the mark.
In the second pic, both the front and hind foot tracks are seen. The bottom being the front foot and the top being the hind foot. Again the mud has distorted the impression some but the third lobe is visible.
The third pic is of the cub. This soil was dryer than where the sow stepped so the claw marks are just barely pin pricks above the toes and the third lobe is visible.
This is in SW Texas, and still the cub's track is large for a bobcat tom. Plus other sign indicated this is a cub traveling with a sow.
Within twenty eight days, I should have pics of the catch.
