Abstract: A combined automatic pet waterer and feeder. A water dish portion is designed to receive the neck of a commonly available soft drink bottle for a storage tank. Water flows from the bottle through a bottle-holding support portion into a water reservoir section for drinking by an animal. A food dish portion has a food container support section and a food reservoir section for receiving food from the food container support section. The food container support section is adapted for receiving one of a variety of commonly available containers. The food dish has an inner wall with a shelf extending therefrom and a ring spaced inwardly from the inner wall. In one embodiment, the ring has a threaded inner surface adapted for threaded engagement with the mouth of a container in which pet food is sold. In another embodiment, the recess is adapted for receiving an open lower end of another type of container, such as a typical coffee can.
