uh oh, is she ILL?

Then last night Pye rushed into the bathroom ahead of me and sat on the seat, peeing away. I waited until she finished to take my turn, even if she is a nasty line-cutter, but when she finished she just sat there rigidly, almost meditatively. I asked her politely to move. When she didn't I went to pick her up and she emitted a low growl. She thinks the toilet is the seat of power. And is she wrong?
