Catster It's official. Social networking sites have gone to the dogs -- and cats. Cat freaks and computer geeks share the fluffy love on Catster while creating purr-fect profiles and linking to their feline friends' pages. Upload enough kitty porn, and your furry companion could be honored as Cat of the Week. Even those without cats can "corral" their own collection of computer kitten pals. Come meet a Maine Coon with an Elvis fixation and twin tabbies named after Russianroyalty. Zoe leaps through the air with the greatest of ease, but Katze has a love-hate relationship with the outdoors. Talk a walk through the cat den, and you may soon agree that it's the cat's meow.
