How to animate a fast cat

Even though the animation in this video is somewhat bad (probably done in a hurry), the slow-motion footage of the cheetah and explanation of how they can run so fast is a wonderful reference!

Sadly I can't find a way to post the video itself here, so you'll just have to follow the link to the Smithsonian webpage:
