Bests & Worsts Reviews from Amazon

I ordered this fountain so that my cats would have fresh, clean water. I felt the stainless steel would avoid the etching problem that occurs with plastic fountains. The parts that are stainless achieve this goal. HOWEVER, the pump housing is plastic and there is a rubber gasket from the pump to the fountain top. After about a month, the rubber gasket developed heavy black streaks of what I can only assume is mold/mildew. This is despite my cleaning the fountain thoroughly every 3 or 4 days. I had to discontinue using it as a fountain because of this - one of my cats has developed urine crystals (probably from not wanting to drink from this fountain) I am now using the bowl part just as a plain stainless water bowl - just like any $10 stainless pet bowl you could buy in Target. I should have just bought several water bowls and washed them every day to start with - would have been less expensive and better for my cats.
