My cats loved the drinking fountains I got for them, especially Sabrina. I did buy them the Drinkwell original design because that's what they liked, but that's the one that's a pain to clean. In fact, now that I'm suddenly without cats (hopefully temporarily), the last one used is still sitting on the floor in the corner of my apartment, unplugged, waiting to be properly cleaned out so I can use it for the next cat(s) in my life.
