It's edited, but hear me out.

This is from a YouTube video called “Copy Cat” by YouTube user TheVFXBro. He, as you can tell by the name, does video effects, specifically with Adobe's After Effects software.

It seems that he moved the cat's paws around in time with his own movements and edited the hands out by using a blank slate image and was showing that in place of where the hands were. He then edited himself into the shot. Either that, or he got a friend to move the paws and edited his friend out of the shot.

Also, when TheVFXBro put his hand down the first and second times, the cat was slightly late to move his or her paw down.

tl;dr: clever video editing
