02/01/10 Update: I now have four cats (as of January 2009) and they all love this fountain. This is my cat Rachel; she is the reason I got this fountain because should would not drink standing water. Cats usually prefer moving water to drink. When you feed only hard food, it is especially important that they drink more because there is no moisture in their meal. If they don't they could develop urinary tract problems. What I like about this fountain is that the filter lasts 3 months (about 2 months if you have a multiple cat household). It also has a large reservoir. As a result, I only have to fill the tank about 2-3 times a week for my 4 cats. I also make sure I clean the entire unit weekly. The pump should also be taken apart and cleaned periodically, which is easy to do as shown in the instructions. I usually clean the pumping mechanism out every two weeks. What I also like about this fountain is that it has a grate in front of the pumping mechanism that prevents a lot of hair from getting into the pump. You just lift the grate up every few days to clean off the hair. Rachel likes her water chilled and the other cats have gotten use to this as well. So you can put ice cubes into the tray and the cats will have ice water in a few minutes. This is refreshing in warm weather; but for my cats I do it all year long because Rachel requests it. There is also an "off-use" benefit to this fountain. One time I burned my fingers and (after putting ice cubes in the water) held my fingers under this fountain for a couple of hours until the swelling subsided. This allowed me not to waste water and to keep the temperature on my hands cold.
