Because my research focuses on animal behavior, I don’t want to spend too much time rigging, especially quadrupeds. Very fortunately I found a very useful model of a rigged hairless cat online. After that is the link to the model.

The model is bound very well, and there are a lot of controllers. Before using this model to animate, I need to group its different controllers and get familiar with what each controller controls.

This group is the body part, and I used this group first to animate.
The entire interface looks much clearer, and no extra controls are accidentally touched during the animation process.

This group is the ears and tail. Once I’ve animate the body, I’ll animate the ears and tail.

This group is an expression.

This last group is a few small controllers, some I’m not sure what it does, and some I might not use in my animations. These are all temporarily grouped into this group and don’t turn it on during the animation.
