I have 3 cats, and they all love this fountain!  It is so easy to set up and extremely quiet. The water is constantly being filtered and gently flows down the top. One of my favorite features is that it is made of ceramic, which my cats can't knock over, and it's dishwasher safe. I have even noticed that they are drinking  alot more water now than they were. I highly recommend the Petsafe Creekside Pet Fountain.
