It's basically a 30 gallon tub, I guess like a really small pond liner thingy, that, yeah, they can just walk up to and drink out of, like it's a natural body of water, only not. It's also filled with "good" green algae and lil' Miss Prissy Pants [Lacey] doesn't drink water unless it's pristine. Hahaha
So, I would probably leave it except that she would probably dehydrate herself instead of drinking it (I've seen her do that, silly girl!).
