Hoodini and Spook are both rather contented with drinking out of a plastic dish, I rinse and fill it about three times a day. I dont think I would need to do it as much if a cirtian tabby cat (ahem, REMUS) wouldn't play in the dish . Remus would prefer if he could drink out of the sink though. Im thinking about getting a fountain for them but Hoodini is scared of running water (He got sprayed with hoses when he was a kitten ) So Im not sure how well that would work
