Abstract: The pet feeder comprises a cabinet structure having a sloping internal partition dividing the cabinet into an upper bin for receiving food and a lower chamber. A metering cylinder is secured under an opening in the partition for receiving food for a pet. This cylinder has a circumferential slot intermediate its upper and lower ends and cooperates with upper and lower paddles vertically spaced on a common shaft and circumferentially displaced so that the lower paddle covers the bottom of the cylinder when the upper paddle is to one side of the cylinder. Rotation of the mounting shaft for the paddles causes the upper paddle to enter the circumferential slot and the lower paddle to leave the bottom of the cylinder so that the amount of food between the circumferential slot and bottom of the cylinder is metered downwardly into the chamber. A food tray is provided for receiving the food and also a water tray with a float valve is provided with access openings to the exterior of the cabinet.
