Okay, after I read all the responses, I broke down and bought a kitty drinking fountain from Petco. It was in the Clearance Bin. It's a Petmate Deluxe Fresh Flow. It was marked down from $39.99 to $19.00 because it didn't have a filter! So I bought a filter. It's pretty cool. It has a small water well and is very quiet. I've picked up all the bowls of water around except for this fountain in the hopes that they'll get the idea. So far the only one I've SEEN drink out of it is Moo. I haven't seen anyone else go near it (they must drink out of it at night when I'm sleeping ) I did put an ice cube in it which DEFINITELY got Eli's attention.
