Help keep your pet hydrated with Bear Bear’s Aqua Buddy Homelife Series Automatic Waterer! Once it’s mounted, simply screw the bowl to the end of your garden hose—the inner valve will stop the flow of water once it’s full and open again when it needs to be refilled. This rust-proof waterer holds 64 ounces (2 quarts) of water and is specially designed for feline friends and canine companions.
