At first I was skeptical as well, but it turned out there is no reason to worry. He picked the right cat for the job. She was totally cooperative and it seems like she thought it was a game of some sort. It's obvious from the video that the cat was neither frightened nor angry.

In fact towards the end of the video, another cat makes a brief appearance (the guy just wanted to present her to the camera, no throwing or falling involved at all) and it serves as a good demonstration what it looks like when they're not in the mood for human shenanigans.

I believe the cat might be a Ragdoll, renowned for being really docile and letting you do things to it[1].
