Drinkwell Reservoir, 50 Ounce

The 50 oz. Additional Capacity Reservoir is an optional attachment that increases the water capacity of the Original Drinkwell Pet Fountain. The Reservoir adds 50 oz. of water, which keeps the fountain filled longer. (Please be aware that the fountain can only accommodate one reservoir at a time.) The Reservoir allows pet owners to customize the fountain based on their individual needs. With the use of the Original Fountain, combined with the 50 oz. Reservoir, the system provides 100 oz. of water which is great for multiple cat households. This product cannot be put in the dishwasher.
