Query: Drinkwell Cat Fountain

In my experience this is a very good drinking fountain for cats. The cat I was taking care of simply could not "see" a standing bowel of water. There had to be movement, i.e. water falling out of a faucet. Other pet drinking fountains produce a trickle with very little movement so the cat would not drink from them. The Drinkwell Fountain produces a nice stream of falling water (that you can vary) and on the whole it works; the cat will drink from the fountain (usually!).I recommend buying the extra capacity tank.Unfortunately I cannot visit this cat more than once a week and the fountain, over time, was not properly maintained by the cat's owner. Clogging and finally motor burnout occurred. But I am buying a new one - it is not terribly expensive, and this cat needs to keep hydrated. If you take care of the fountain as instructed and do not neglect it it should, however, last a long time.
