I have three cats and a large dog who have been using the Premier Pet™ 60 oz. Pet Fountain for over a week now and with great success. All of my animals immediately took to the water fountain and have seeming enjoyed the fresh and constant flow of clean running water. My cats kept knocking their water dish over in the process of drinking to create "flowing water" that wasnt standing still, this fountain has helped stop them from that headache of a mess. The fountain is very easy to assemble and use, as well as take apart to clean. It runs very quietly and I wouldn't know it was on without hearing the trickling sound of the water hitting, which I find to be relaxing!
