I recently acquired a Drinkwell kitty fountain, and will be setting it up tonight. Cats are highly susceptible to kidney problems, and the more clean water they drink, the better off they are. Previously I had a Petmate fountain which worked quite well, but was a pain in the butt to clean. I may order a replacement part and get it up and running again, however, as it does provide clean running water and having 2 sources for the kitties could only be good. If anyone has any comments/ideas about such products, I'd like to hear them!
