Not bad for my first time doing a quadruped run. I had to do it on 1s since it is such a fast motion. I studied footage of a lion running to get the motion. The keys are fairly similar to a biped walk. Starting with the front legs contacting, then the front legs move under the body as the hips and back legs catch up. Next the back legs make contact and begin pushing into the next stride. The cat is in mid-air briefly before the front legs land again. I enjoy studying and breaking down motion.
