I have tried a couple of fountains but they both threw water out of the water basin onto the floor faster than I could fill them. Nothing scares Smokie, and she loves it when I let the water run in the bathtub so she can play in it. I'm afraid something with a reflective surface wouldn't scare her, but as she can spend 10 or 15 minutes at a time in front, pawing at 'that other cat back of that glass' she would do the same thing with the fountains. I wouldn't mind the water if she was doing it in play, but not all the time when she wasn't around!
