A pet toy having a track with an attractant or lure that preferably is a ball that rolls around the track when a rocker arm is rotated by a rotary drive. An animal proximity sensor that includes a switch energizes, de-energizes and/or reverses direction of the drive when actuated by a pet. The arm carries a counterweight and is supported by bearing that rides on a base of the toy spacing the arm so it clears an onboard power supply. A preferred toy has a fulcrum resting on a support surface about which the track rocks during arm rotation and can include a rib that provides rotating point or line contact with the surface during rotation. An acoustic resonator recess, e.g. channel, formed in the track amplifies the sound of a ball rolling in the track producing a distinctive sound that attracts pets, e.g., cats, and is pleasing to humans.
