Abstract
A large hollow ball is centrally and symmetrically mounted around an axle having ends which extend beyond the outer wall of the ball equally on diametrically opposed sides. The two axle ends are secured within retainers provided on a ring which orbits the center ball. The ring has a center track on which is contained a plurality of balls. In operation, as a cat propels the center ball, the ring is free to pivot about the axis and as the ring pivots, the balls contained in the track roll back and forth.
