Wow, that sucks! I had left my 4runner's rear window open for a couple weeks once, a cat made a nice little nest in the coverall on the back seat (could tell by the shape of said coverall and the fur all over it) and pissed on the floor in the front seat...a lot. Fortunately I have no carpet, so lots of scrubbing and it was taken care of. I might flip out and kill every cat in my neighborhood if that happened to my Tundra.
