And a typical (and beautiful) one at that. When I saw that, I went "Of course." Felines seem to have a knack for knowing the best moment to eff with you out of sheer vengeance. My guess is you had been at that for awhile and thus ignoring it, so of course it decides to get in your face at the most inopportune moment. My cat is the same. I'll be ignoring her for hours writing and recording parts. Then I'll sit down to mix over speakers and THEN she decides to start wailing her disapproval. It's unreal.
There was a story related in the book "Beyond Words" (great book on animal consciousness, terrible title) where a Russian hunter tells how they once scared off a Serbian tiger from its kill. That same tiger would destroy their traps, scare off animals that came close to the hunters' bait, roar and scare everything away, basically not let the hunters hunt for a year because of that one infraction.
That kind of vengeance takes great skill and effort. It must be admired.
