National Cat Day is one of the finest and furriest holidays of the year. You can celebrate it by playing co-op kitty titles like Cat Quest III and Cats on Duty, or you can celebrate with the fresh single-player demo for Gori: Cuddly Carnage from Wired Productions. Gori is a surprisingly stylish 3D action game starring a cat on a hoverboard who has to grind rails and slice up lots of cutesy zombies.
