Exclusively for Prime members: Amazon has this Aspen Pet Cat and Dog 4-gallon Gravity Waterer for an amazing low price! (NOTE: Temporarily out of stock, but you can order it now to lock in the price)
The Aspen Pet Lebistro Gravity Waterer provides pets with a delicious source of fresh water with less refills required for pet parents. For pet parents with busy lifestyles, this gravity water bowl for dogs and cats ensures easy access to an extended supply of water. The reservoir gradually dispenses water as pets empty the bowl for fresh, better tasting water. With a twist-lock bottle, the bottle fastens securely to the base for stability and is easy to take apart for convenient hand-washing.
