Keep water fresh and always available for your pet with this durable automatic pet drinker. Simply fill the reservoir with water and place it back into the base to have water drain into the bowl portion to be enjoyed. There are two sizes available – the 4.5 Liter drinker for larger dogs or multi-pet homes, as well as a smaller 2 liter for toy breeds and smaller domiciles. The base comes in orange, Blue, or coffee, with a matching screw-on lid on the water tank. Pairs well with our Automatic Pet Feeder.
