The kitty in “the” video was posturing and playing. (I enlarged it and stopped frame by frame, and didn’t see any wire.) There are plenty of similar videos. Several of my cats would do that exact kind of thing all by themselves, with nothing else present but... some dastardly catnip leaves on the floor! But, if you want to imagine foul play, suit yourself.
If you want to pretend no foul play, suit your self.
