I drew over the 2 previous Eadweard Muybridge cat images. I simplified them down so I could see the spine and leg placements.
You can see the extent to which the spine stretches and how it bends when the cat brings its back feet in to push off for another jump. You can also see how the back foot is placed in almost the exact same place the the front foot was. Cat are very sure footed and use this to keep balance and so they know its safe to put their foot there.
This one is a good one to see leg movement and foot placement. All the legs move independently when the cat is walking, but as the cat begins to pick up speed the back legs begin to move in unison to push the cat forward.
