Children form a circle around the room, with hands joined. A "cat"
is chosen to stand outside the circle, a "rat" to stand inside. The
players are friends of the rat, and raise their arms to let him under,
but keep them down when the cat tries to get through. The cat chases
the rat in and out of the circle, among desks and over seats, till the
"rat" is caught, when a new cat and rat are chosen.
