PayItForward,

I believe you're thinking of the Drinkwell Fountain. This is a PetMate Fountain. The reservoir is smaller.

Denyce,

I have to clean mine out once a week. They don't play in it but it does catch alot of cat hair.

Noahsmommy,

With 7 cats, I've noticed that I have to refill it every other day. I usually fill the "well" when I'm lazy and don't feel like filling the reservoir. My cats really love it! I keep other bowls of water out as well, but they seem to gravitate to the fountain. That's a good thing!
