I am glad Stedman and Tate like their new fountain!!
I have two Pet Mate drinking fountains. One is a small and the cats drink out of that one. The other is a large and all the dogs drink out of that one. They all really love the fountain and prefer them over just a bowl of water.
With the fountains I have it says to change them every 30-60 days but I change mine every two weeks to make sure they stay nice and clean. I will take the whole thing apart, including the pump, and really clean it thoroughly about twice a week and just wash it out about every other day. The water really does stay clean, cold and fresh!!
The small one I have to fill up everyday but with the large one I fill it up every other day because it has a big resovoir.
Anyways I really love them as do the dogs and kitties and I wouldn't ever be without one again!!
