One embodiment of a pet toy having a control module, active triggering module, and passive triggering module. Our device is an interface between a pet and pet toy or other useful device. A pet can trigger at will a moving highly collimated light dot for exercise, entertainment, mental stimulation, education, and even surrogate companionship in the absence of a human caretaker. Pets that fail to learn triggering behavior will benefit from pre-set play periods as programmed or selected by their caretaker and/or passive activation such as infrared detection or another proximity sensing switch.
