Wow. 12 Saints. That is so cool. I'm jealous. Looks like you have a nice set up for them. As for drinking, I think it's normal for Saints to drink a lot. Maxwell's a little water pig and empties his dish every time. I bought him a Monster dish and he can guzzle. I'm not worried about it at all. My friend has a Saint and hers is the same way. Saints do everything big. Sleep, snore, burp, eat, drink, play, poop. Max will drink from any dish available. I have to put my Cocker's dish out of Maxwell's reach. The most valuable thing I bought for Maxwell has been the baby gate. It's awesome. He could knock it over with one paw but he's scared of it and won't try to push it over. We gate him in the hall so we always have a nice big place to keep him. He sometimes sleeps there and when we work, we know our cats are safe. During the day we keep the gate on but raise it higher so the cocker can get at his food and Maxwell can't. It's been a real life saver.
