Premier Pet 60 oz Pet Fountain for cats and small dogs is really a fresh idea that makes me feel like I am treating my pet the best I can. Having 4 free-falling streams encourage pets to drink more, and she does now. It makes me feel much better because proper hydration supports urinary and kidney health. This fountain is very easy to clean and comes with a carbon filter, foam filter, pump and a power adapter. No wasted water is always a wonderful thing and your pest deserve fresh water all day long. Replacement filters are sold separately and easily available. This will be a permanent fixture in our household and I know Lucy appreciates it.
