Exploiting an innocent animal's cruel death for profit or recognition is the problem...
If a man (or woman) killed another human being in a sick and unusually cruel way and video-taped it there would be a lot more outrage in the community concerning the footage, and whether or not it's art. I know a cat is not a human, but we are all animals and we should respect all creatures on this earth.
We are no better than any other species, including the ones we keep as 'companions' or work/livestock. My thoughts are still jumbled, so please excuse me while I go throw up...
