Actually I've never seen it happen. THat chair back has been a Dark
Nocturnal Throne for over four years--Nox has the top flattened down
pretty well.

I have, however, given Nox catnip and as she attempts to roll in it and
poly, she's fallen off the chair, then drawn herself up and with great
dignity, like an Olympic diver receiving high scores, takes credit for
that intricately designed maneuver that she just executed solely to
impress us masses, on purpose of course.
