I'm thinking about getting a new fountain for my cats. I currently have a Drinkwell 360 in stainless steel. I've had it for several years, and the cats like it. But...It's gotten progressively harder to keep clean and I have to clean it more and more often. It's a pain to disassemble all the bits and pieces. I will never go back to plastic, so I'm thinking about getting one of the Petsafe ceramic fountains and I'm wondering if the ceramics are easier to care for long-term than the stainless. Any thoughts or recommendations?
