I have a drinkwell fountain and Sunny,Cirrus, and Sky loved to drink from it. Storm would drink from it occasionally but preferred the water bowl. Well I had to stop using it because a certain orange cat was having too much fun playing in it. Everyday I'd find a large puddle of water around it. I hope that some day Sunny will outgrow this problem. I also have to keep their water bowls inside of clean litterboxes because Sunny will sometimes play in this water too. BTW I was able to use the fountain for almost a year before I had to shut it down.
