My cats love their fountains, and so do I. They are beautiful works of art, lovingly handcrafted to be safe for my fur babies and easy to maintain. The pumps are silent, so all you hear is the soft sound of the water. It only took a few hours for all six cats to adjust. Some drink from the bowl, some from the falling stream and some from the bubble-up point….but they are all drinking more and staying hydrated. Thank you for such a valuable service!!
