Great news about Atticus, Mao!

I've heard great things about filtered recirculating waterbowls being helpful, but don't have any ideas beyond that. We use the Drinkwell brand pet fountain. My cats are very enthusiastic users of it, but I worry about the motor burning out (again -- long stupid story...). Spencer mentioned something about a new breakthrough in these waterbowls, but I don't remember quite when or where he told about it.

Good luck.
