Treat your pet to fresh, filtered water with the large-capacity 3.1 l Petwant PW-108 fountain. It will help you keep your pet healthy and hydrated. Constant water circulation prevents bacteria growth, while filters remove odors and smells. The free-falling stream of water encourages your cat or dog to drink more, which can help prevent urinary tract and kidney disease. The Petwant large capacity fountain is ideal if you have multiple pets or a large dog. The square fountain design is large enough for several pets to drink from at the same time, with minimal water splashing out of the fountain. The Petwant PW-108 fountain uses a carbon and foam filter to remove bad taste and odor from your pet's water, keeping it clean and fresh at all times.
