While many cats do prefer water from a fountain, some do not. So I advise that if you're going to try a fountain, get it from someplace that will allow easy returns if the product has been opened and used. I tried a fountain with my kitty once. She stared at it for a couple hours and did not know what to make of it. After the first few hours she decided that it wasn't going to shoot poison darts at her or anything, but still did not know what to make of it beyond that. So she ignored it. After a couple weeks of it constantly running and my trying to show her what to do, I returned it.
