  • Patent number: 6701872
    Abstract: An apparatus for exercising a curious animal such as a housecat comprises a laser pointer mounted on a shaft driven by a geared motor mounted on a pedestal. The rotatable shaft is preferably generally vertically disposed and the direction of the pointer is preferably obliquely downward so that activation of the motor causes the spot beam of the laser to track around the pedestal with a vector of motion to attract a cat into interaction with the spot beam. In a further specific embodiment, the laser pointer may be mounted on the head of an oscillatory air circulation fan with a pedestal. The oscillation of the spot beam, together with the air movement of the oscillatory fan, further stimulates activity in a cat while conveniently inducing convective cooling.
