Thanks Scott! I have the Petmate Fresh Flow and I think I am going to return it. I like to be able to tell how much water the they are drinking and I can't do that with this. Also when I took it apart to clean, there was quite a bit of hair floating in the water. I think I kept their water cleaner than this does.

Something else that I read a while back was to feed them their water and food in ceramic or stainless bowls to avoid the black fungus they can get on their noses. Sage
