Abstract: A control system for accessories used with small animals and pets comprises an accessory module, such as a pet flush toilet, small animals feeder, or small animals trainer, coupled with a detector systems that senses the presence of said small animal or pet at the needed location and transmits appropriate signals to a logic control segment designed for the particular accessory module employed. Such detectors do not physically restrict small animals or pets and can be passive infrared or proximity in their principles of operation. The preferred embodiment is demonstrated by controlling an accessory module comprising a pet flush toilet system with a delay-reset logic control.
