It's a well-established fact that cats make excellent alarm clocks, albeit ones that tend to go off well before you want them to. But I have recently become aware that Emily has a uniquely well-honed sense of both how much time has elapsed and how much time should be allotted to a particular function.
Especially when that function takes place in the bathroom. I haven't sat there with a stopwatch or anything, but Emily does seem to enter the Throne Room at regular intervals.
You'll be sitting there, performing a necessary chore, maybe reading something (possibly playing Video Poker on your iPod touch), and suddenly a cat pushes the door open, walks right up to you and gives you this look that clearly says, "You're still here? Really?"
Oddly, she seems to respond to an impatient "Okay, okay, I'll get a move on," and exits the bathroom. But five minutes later, she's back. This time, she not only gives you that look, she usually bites you on the side of the thigh, knowing full well you can't exactly get up and chase her with any hope of success.
By the third visit (hey, the book was good!), she'll just give you the "Get off the thunderbucket!" glare, then go out into the bedroom and make a bunch of loud noise on the metal closet door. That's usually enough to propel you off the john, and as you waddle furiously into the bedroom, she's back on the bed, looking at you coolly, as if to say "Finally, you're out."
I like to think that Emily believes she's helping us save water and electricity, but I know her too well. She just does it for the evil lulz.
