Ah! PetMate Fresh Flow - I don't know how we would do without it now that we have it!! I bought mine either off eBay or Amazon and it was used. This guy bought it and his kitty didn't like it so he packed it up. It appeared to be brand new, though. It is the "Deluxe" which I think just means it holds more water. The flow is adjustable and that might be a deluxe thing - not sure.

At first everyone *did* play in it but only a short time. Dylan likes to drink from his paws so sometimes there is a mess but no more than the water bowls.

With the five kittties, I have to really clean it out well everyweek and I use an old toothbrush at the grungy areas - like at the top of the ramp where the water comes out, then buff it all off with a dry towel & refill.

The motor is simalar to what is on a very small aquarium - for sound comparison. I don't even notice it except - like someone said - the water kinda gurgles if the level gets low.

Mine seem to drink TONS of water but I also think alot does into the air because I fill it up a nearly everyday and I KNOW they never drank nearly that much water before..or maybe it is just the fact that it is cold and clear and fresh?
