I have a cat fountain that I bought at a discount store and the thing moans and groans when it runs. It's terrible and I can't leave it plugged in.

THIS fountain is a game changer. Who knew that the pet fountain was supposed to be so quiet? I didn't know that was possible.

Putting it together was easy and as long as you followed the directions and knew that the piece that says front is actually the front, you will be good. 

Definitely love this thing because of the quietness. My cat likes it also because he can go to it anytime during the day, because I don't mind leaving it on all day. It's quiet.
