A generally circular enclosure is provided defining a generally circular track about which a prey decoy is located and travels. Openings or apertures in its housing permitting the prey decoy to travel about the track. The prey decoy is secured to a rotating wheel that imparts a rotary motion about the circular shaped track. The prey decoy is further spring urged in a vertical direction, perpendicular to the plane of rotational motion. The track opening has at least one break, making it noncontiguous. As the decoy is deployed about the track and impinges against the housing at the break in the track, the decoy is urged downward, and subsequently is urged upward when it reaches the track opening at the opposing side of the break. This circular motion in which the prey decoy appear to be moving upward and downward as it travels about the circular path stimulates the animal to paw at and engage the prey.
