This product only works with the Original Drinkwell Pet Fountain (50 oz. size). The Additional Capacity Reservoir and Additional Capacity Reservoir Plus are optional attachments that increase the water capacity of the original fountain.

Drinkwell Aqua Garden, a hydroponic, 100% organic wheat grass garden that utilizes the continually circulating water of the Drinkwell Pet Fountain to grow cat grass in a matter of days.

This Fountain is big enough to keep larger dogs properly hydrated while keeping water in the bowl. The Big-Dog features a snap-on lid, 5-inch bowl wall to help keep water in the bowl, rubber feet to prevent sliding and a built-in reservoir.

The NEW Drinkwell Cleaning Kit provides product owners with a convenient and easy solution to keep their fountain clean with 3 specifically designed brushes for the bowl, intake tube and motor.
