Kitties love dripping or running water. I read somewhere they like it because it's more oxygenated and because, in nature, if it's running, it's more likely to be clean.

I have one cat that drinks out of the toilet. And one dog who is a poop eater, prefereably the poop of our other dog. That's completely gross. The worst thing is the dog who licks turds also likes to sneak up, early early in the morning, and lick me or my husband on the mouth before we're fully awake. One of these mornings she's going to catch my husband when he's a little more conscious and he's going to throw her across the room.
