Hasn't happened to us, or Amber:

It is very disturbing to see the headless body of your cat in the sink. This is an animal that I have slept with nightly for ten years, who burrows under the covers and purrs against my side, and who now looked like a desperate, fur-covered turkey carcass, set to defrost in the sink while it's still alive and kicking. It was also disturbing to see Rich, Mr. Calm-in-an-Emergency, at his wits end, trying to soothe Rudy, trying to undo the garbage disposal, failing at both, and basically freaking out.

Not to worry, everything ended up just fine. Well, except for my now-very-well-split sides.
