Cats and suspicion are the main ingredients in this multiplayer game. Players are divided into two teams: cats, who are aware of their identities, and players, who are trying to figure out who among them is feline. The players must discuss and vote on which of their own group to eliminate.
The game's objective is to identify all the cats, either by deduction or by getting them to make mistakes that reveal their true identities. The game takes place online, allowing players to join and play with others without the need for a download or registration.
