Cats who purr-form patty cake together. See SWNS story SWCATS; Patty cake is a hand-clapping game normally for children singing their favourite nursery rhymes on a playground. But paw-clapping Olle, Lillebror and Ferdinand, known online as the Patty Cake Cats, have the bizarre habit of playing the game with each other. The British Shorthair trio wave their furry arms around and clap their paws together, as if they are playing the game. Affectionate owners Helena and Olof Rogbrant have captured their antics on camera and posted videos of them on the feline's own social media channels.
