Cats are smart, really smart, which is why they need a smart litter. After leaking an unbranded video online of our deck-scratching felines, our smart cats were everywhere. We took the best of the online content along with some of our own and made a tumblr dedicated to smart cats everywhere. To complete the experience, we even made a game in which you could play the smartest of cats in a game of chess. Who'd have thought that a bunch of cat videos and cat gifs would do so well on the internet.
