Each of the participants pair up and sit on the floor spread out. A pair is chosen and between the pair they decide who is the cat and who is the mouse. The cat chases the mouse around the room until the mouse decides to sit down next to a pair. When that happens the person on the other side of the person the mouse sits next to gets up and is now the mouse. If the cat catches any of the mice, the roles are reversed and the cat becomes the mouse and vice versa. The game contiues indefinitely until the chanichim are tired.
