There's the movie "Cats & Dogs", basicly the movie is about how the two sides cats and dogs battle each other while one of the cats becomes the evil genesis type. It didn't do too well in theaters but it was fairly good for what it was.
Quote:This talking-animal action comedy from Lawrence Guterman, the co-director of Antz (1998), follows on the heels of the Babe and Dr. Dolittle films. Unknown to humans, a secret war has been raging between cats and dogs for eons, but a fragile truce has long held the order of the animal kingdom in place. Now the balance of power has tipped, as a researcher, Professor Brody (Jeff Goldblum), is about to invent a vaccine that will erase all human allergies to dogs. This is too much for the autocratic Mr. Tinkles (Sean Hayes), a white Persian kitty bent on world domination. The Brody home becomes ground zero for the renewed conflict between feline and canine, with a young Beagle puppy named Lou (Tobey Maguire) caught in the middle as the new point man for his species' cause. Cats and Dogs co-stars Elizabeth Perkins and Alexander Pollock, as well as the vocal talents of Susan Sarandon, Alec Baldwin, Jon Lovitz, Michael Clarke Duncan, and Joe Pantoliano. ~ Karl Williams, Rovi
