Has your cat ever drank from the toilet? Is your cat big enough to even try? We've caught Dusty drinking from the toilet twice. The first time we redoubled our efforts [I](by "we" I mean my dad because he never closes the stupid lid)[/I] to keep the lid closed when not in use. The second time was a slip on someone's [I](dad's)[/I] part. The water was clean both times luckily. Our other cat, Sassy, is too small to even try to drink out of the toilet. Dusty is a behemoth of a cat and looks even larger when he stretches out, so it's no surprise he could lean over the seat to drink. We have fresh water constantly available but the only conclusion we could come to was the toilet water was cold and that's why he drank out of it.
