Apparently the little buggers got in through the evaporative system and into the front passenger compartment. Rats/mice can pretty much chew through anything, and all the plastic in today's car are no barrier.

I have a cat, but I think she's too comfortable. Spreading all the warfarin from Long Beach's Health Dept around and under the car I think will work. I'm also moving the car daily, something I didn't do this spring.

Also, although State Farm paid graciously, I don't think they'll do so a second time.
