Bouncy ball with a tail assignment

This is an assignment I created of a beach ball and a bouncy ball with a tail. It's more of a character.

I tried to animate the tail ball to act like a cat.
It was quite hard looking for a proper video of a cat jumping or bouncing for reference.

 

I found a video of a giant beach ball falling from a building.

I found it as a good example of bounce physics.

Trying to focus on the hip and tail of a cat,

this image helped by showing that the tail.

 

These videos show the tails animation when the cat jumps, it is stretched and used for momentum.

All references are from Youtube and Google.
