I had the Fresh Flow and my cats loved it. They're all boys and I'll do anything to get them to drink as much as possible! However, it stopped working and I suspect the pump burned out after only a couple of months. No mention on how to replace it, so I'm pretty disappointed in it--what a waste of money! I've just ordered the Drinkwell mainly because it says the pump can be easily replaced. Not that I have the Drinkwell yet to be able to recommend, pump replacability should be a main consideration. I wish I had known that would be a problem. Now, fingers are crossed that the extra filters I bought will fit the Drinkwell. I'll let you know how my boys like it, but I'll bet they're going to love it! BTW, I couldn't find it in any of the local pet supply stores, so I had to buy it online. The best price was at

If you decide to get it, you might want to go ahead and order the extra filters, because you'll need them if your cats use it.
