In the winter they like to stay warm by the engine, I know this because in my old integra after A cold night in the morning I would pop the hood and notice bones on the engine cover, it only happend twice but the second time I didint pop the hood one morning and A few days later I found grease stains on the cover it was nasty to clean up. Rats chewing wires is weird, I would tie A street cat to one of my tires if that helps
