You guys clearly don't have pets in the family do you?
To me its how amazingly well this guy cut voices in over the video. He brought it to a whole new level by making up some half sensible conversation that the animals are either having or something they are talking about that really truly fits the video. I also have to respect how well he did the voices while paying attention to the facial expressions and where they are located at in a room, or under a blanket, ect. He will muffle his voice appropriately or make his voice sound further away as though it were really the animal talking. It was a cut above the rest of the people I've seen with lame videos were all they do is put their voices on top of a video and its horribly done... just saying, the guy has skill.
