Advanced Animation Cat running

the next thing we had to do was to learn how an animal was running.
so what I did was learn everything about a cat running. how flexible it gets, how fast its legs are moving, where and when would the paws land.

here's the full animation.

some reference was used for this. but mostly from what I remembered. while looking at a video.
here is the video.
