I have a 9 month old male cat. He makes so many messes. Several times a day he was turning his water over and also putting his food into his water. We were constantly cleaning up the floor and cleaning out his water dish. The Drinkwell Fountain solved this problem. He is no longer turning it over and for whatever reason he doesn't even put his food in there anymore. I love that that the waterfall aspect is adjustable. It's easy to set up and easy to clean. The fountain kind of filters out any little thing that gets into the water as it cycles through. It's made from good durable feeling materials. Not cheaply made.It's the perfect size! I'm more than happy with it and so is Noble
