large capacity fountain. My cats really love it, the screen in the front catches a lot of cat hair and other gunk which means you have to take it apart and clean the pump far less frequently than with my old fountain. Still working with no problems after owning it for more than a year, my only complaint is that the linkage in the cord is really close to the plug side, not the pump side. What this means is that if you have things between your fountain and your outlet, you have to go around them to disconnect the linkage. If that link was closer to the pump side you could more easily disconnect it for cleaning purposes. It is a small thing to complain about, and it seems that every fountain is like that, but when you have to reach behind your fridge to disconnect it every time it needs cleaning it gets pretty annoying.
