A cat is asked to clean the office floor, so it hops on a robot vacuum and starts fighting the other cats for dust. Eight cats ride vacuums around the office collecting dust. Collect enough and you can fire a blast that knocks nearby cats and furniture away. Fall off the floor and you drop everything you were carrying, so no lead is safe until the timer runs out. The office walls break. Knock a chair into a desk, set off a chain, and you've made your own shortcut. Pick any cat and coat you like. To play with friends, create a room and send the invite code or QR code. Two to four people can play, and computer cats fill the empty seats. Online play needs a Friends Pass for each player, bought once. Matches against computer cats are free. Available in English and Japanese.
