ABSTRACT:
A device is disclosed which comprises a drinking fountain for animals in the configuration of a free falling stream of water, or continuous waterfall. A pump moves water from a reservoir upward to a discharge ramp, or ramps, where water spills over into a receptacle. The reservoir and receptacle may consist of the same part. The cascade of water takes advantage of a preference demonstrated by animals for moving drinking water. The waterfall action also aerates the water and increases freshness, by breaking the surface tension of the standing water and drawing in oxygen from the atmosphere. Filtration of the circulating water in this self-contained system is easily accomplished.
