The automatic pet watering apparatus provides for very limited human intervention in the operation after installation. No power supply or animal training is needed. The saddle valve provides for supply hose attachment without need of plumbing tools or expertise. Essentially, the only component of the apparatus which may require adjustment or replacement is the inlet valve. The overflow hose provides a safety measure should the valve ever stick, allowing drainage to a chosen area. The semi-ellipsoid shaped bowl housing also has a cavity whereby mass may be added. Flexible supply hose, feed hoses, and overflow hose provide for convenient location of the apparatus components. More than one feed hose can be provided, and more than one bowl housing with bowl can be provided, allowing one reservoir to feed a plurality of bowls, negating added expense when more bowls are needed to either feed more animals or feed one animal in more than one location.
