Empress is on the Throne!
This is Empress. She's a four-year-old seal point Siamese who has taught herself (!) to use the toilet. She gets up, does her business, then sniffs around the seat when she's done, to make sure she hasn't left a mess, and gets down. She's also taught her sister Cocoa to do the same, although Cocoa still tries to "cover things up" like in the litter box, resulting in occasional muddy pawprints on the toilet seat.
