I am also concerned with bactiria growth in the plastic. (and just the chemical leaching in general that plastic does) I have thought about removing this great little pump from this cheap fountain and making my own out of a ceramic bowl.Originally Posted by oregpsnow
I had a Catit fountain but it was expensive, noisy and hard to clean. I was also concerned about bacterial growth in the plastic over the long term. I decided to design my own. I got a ceramic dog bowl, a cheap aquarium pump, some tubing and an airstone. The pump can go anywhere as long as the tubing can reach the bowl. Put the airstone in the bowl and you have gentle bubbles. My picky cat loves the bubbles. Every few days dump the water in the sink and put the bowl in the dishwasher. No muss, no fuss, no filters. I replace the airstone every few months so it doesn't get too yucky but they only cost about $.50.
