International ClassA01K 039/012AbstractAn automatic pet feeder comprises a tubular food reservoir with a food replenishing port and a feeding port. The food replenishing port is in the upper end of the food reservoir and is sealed with a cap when in use. The feeding port is located adjacent the lower end of the food reservoir and has a pivotally mounted cover plate, sealing its otherwise open end, that can be pivoted out of the way by a pet to gain access to food in the feeding port. The bottom wall of the food reservoir is inclined to cause the food within the food reservoir to flow into the feeding port as food is consumed by the pet. The automatic pet feeder has an offset handle for suspending the pet feeder that helps to maintain the pet feeder level and a removable support stand that permits the pet feeder to be placed on the ground. A supplemental cup is also provided for water, trial foods and the like. | |
