Give your pet unrestricted access to food & water with no mess. The Combo Feeder & Waterer create the perfect pair for feeding & watering. This combination food & water dish features a durable plastic base with Microban antimicrobial to protect against the growth of stain & odor-causing bacteria. One side contains a removable food bowl & the other a self-filling water reservoir. Simply fill a two liter bottle (not included) with water & attach to the base. Gravity flow design dispenses just the right amount of water & won't overflow.
