Best way to spend the hours before Super Bowl XLII kicks off? Puppy Bowl IV, of course. Animal Planet is returning with its annual doggy romp at 3 p.m. EST (with repeats at 6 and 9), in high-definition for the first time. Harry Kalas, the voice of NFL Films, is also back to call the “play-by-plays.” The Animal Planet website has a roster of the cuddly pups. My faves are Emma and Tucker. Feline fans wll be happy to know that The Kitty Half-Time Show is also back.
