We really wanted a fountain to encourage one of our cats to drink more. This is perfect. We haven't had it long but they all seem to like it. I refill it easily by pouring cups of water into it daily to keep the water level high. I think they really like the moving water and the filtration. They tend to drink from the top. There were a lot of parts to put together but it didn't take long. I put it in a hallway next to an outlet, on a rug. It's our upstairs water bowl. The filtration keeps their hair out of the water! Its great.
