As Claude, the cat, begins to moving around the gameboard, all players at the same time quickly turns their mousemover wheels, trying to keep their mice away from Claude's mouth. If a mouse is caught by Claude's teeth, then that mouse has been catnipped! All play stops. The owner of the mouse takes a yellow token and places the mouse back on its turntable. The game continues untill all of the yellow tokens have been collected. The player with the fewest tokens wins the game and is the Big Cheese! In case of a tie, the players have a play-off round.
