Our cats always sit outside the bathroom door in the morning, waiting for the flush.We have three cats and a dalmation. Spot likes to drink from his bowl, or from muddy puddles, when we walk in the woods. He just wants to wet his whistle.
But one of our felines, Shadow (alias "Demon", "Satan", "damn cat", and various other epithets), has to follow me to the pot. He likes swirlies (almost as much as the top stair step, in the dark)! He will jump onto the seat, and stick his head right into the bowl, dipping into it. I have to act fast, to slam the lid, befoe he gets there. Damn stupid cat...
That's the difference between cats and dogs in a nutshell. Our dog would drink out of anything including the koi pond in the backyard, but our cat was oh so finicky. Whenever she was enjoying a drink at the loo, we'd gather around and laugh at the sight (it was pretty hard not to), and she'd just poke her out at us and give us a curt "meow!", as if to say "Yes humans, I am drinking out of your toilet. I tastes better than what you put in my bowl, ok?" And then she'd go back to her drink.
