An automatic watering device for the pika (Ochotona rufescens rufescens).

: An automatic watering device was developed for the pika (Ochotona rufuescens rufescens), using drinking nozzles for rat and plastic pipes. This device was used for at least one year without any mechanical troubles, resulting in labor saving of animal caretakers. No difference in growth was observed between pikas reared with the automatic watering device and those maintained with conventional watering bottles.
