Stainless Steel Water Fountain

Hello, i'm having a very hard time finding a stainless steel water fountain for my cat. I currently have a plastic one and think it may be causing a puffy chin on my cat. I heard stainless is less likely to get moldy. I clean the fountain more than once a week and it seems to get dirty quick.

Anyone suggest a fountain and where I can get it?

Thanks!

There are a few now, however be prepared as stainless steel is more pricey than plastic.

Petmate's version - although it looks mostly plastic, I'm not even 100% sure that's stainless steel on there (Another link to Petmate's site on the fountains)

This one I haven't seen before
