After reading posts here about water fountains, I
bought a Drinkwell at Petsmart.  Our two kittens
(in a separate room because they're FeLV+) took
to it almost immediately.  That was a two weeks ago
and I just got another I ordered from DrsFosterSmith
(fountain + reservoir) for our three cats in the
main house.

Thanks to all for the recommendation.
