Yeah, I can believe it is CG as I can stop my fan with little force. The weight of a cat would horribly throw a fan off balance and it wouldn't work that well. There's also some shadows that don't work out right, especially since that TV int he background has curved glass. Also at the point the cat lets go it would go out the windows, not straight out like it did. The catwould have had to let go when it was pointing at that picture just left of the tv. Also the picture next to where the cat hit didn't budge nor did the curtains move from the little bit of wind that the cat would have generated just before hitting the wall.
funny though.
