Although I've animated some 4-legged animals in the past as a traditional animator, however, I don't think I did them that well back then. Achieving subtle acting and performance in hand-drawn animation was, and still is very difficult. Not that it's any easier to do in CG, but it is achievable and believable.
It's been a much-delayed interest of mine to at least try to animate quadrupeds in CG. And so, I decided to take a realistic creature course at Animation A Team with Rob Hemmings, to learn some new approach and techniques of how to do this.
This is the thumbnail sketch for the story idea of "Gotcha!", ( originally called Cat Chase), which I consider my first successful attempt in animating a realistic quadruped animal as a 3d animator.

So below are the final results. Enjoy!
And here's the same animation with fur render.
