  • Patent number: 5657721
    Abstract: Local and remote motion detectors sense the presence or movement of a cat in an area near the toy and in an area remote from the toy. In response to the motion detectors, an electric motor moves a target to attract the cat. A device disconnects the target from the electric motor, when the cat subdues the target, allowing the target to stop moving while being held by the cat and giving the cat an artificial sense of "post-kill" satisfaction, while simultaneously prolonging the component life of the toy.
