Abstract
A filtered water system for pets that includes two (2) gravity feed units, one (1) of which dispenses filtered water and the other which dispenses dry pet food. The filtered water gravity feed unit includes a breather tube such that when the water level drops below the breather tube level in the water bowl, air enters into the breather tube equalizing the pressure inside and outside of the water bottle. This allows water to fill the water bowl to a level where the pressure inside the water bottle is equal to or less than the pressure on the water in the water bowl and water stops flowing. The water gravity feed unit includes a filter capable of removing some contaminants from the water.
