MTV has refused to air a public service announcement created by People for the Ethical Treatment of Animals (PETA) that encourages spaying and neutering of housecats. To drive its point home, the PSA features two animatronic cats, er, getting frisky. "In this instance, we found the ad to be too graphic," an MTV spokesperson tells TV Guide Online. In a letter to MTV CEO Mark Rosenthal, PETA responds: "We are flummoxed by this rejection. Is carnal knowledge between cat puppets more problematic than seeing one of Sisq&#243's "Thong Song" dancers waving her buttocks at the camera?" Touch&#233.
