Misha Demonstrates Proper Squatting Posture

I've been saving this one for a rainy day.

When I first caught my cat in the act of sink-urination I was horrified. But upon further contemplation, I realized that this phenomenon might potentially work to my advantage. I mean, she always aims directly for the drain and there's often no evidence of the transgression at all, and there's no clean-up involved! No scooping, no gagging, no lingering stench.

So how far removed is toilet training, really? Is it a bigger inconvenience for the cat or the owner? The training itself seems more involved than I'd generally like, but the pay-off is... well, who can put a price on Misha's accomplishment?
And if you have multiple cats?
Well, don't overlook the FAQ.
