That sucks. I'd keep an eye out for it on your new hybrid NSX though too.
Honda and Toyota are trying to lead the way in environmental friendliness and have been switching to soy-based insulation for their wires. There's been so many warranty claims for rodents chewing through wires (especially on the hybrid vehicles) that Honda has developed rodent-resistant tape for the techs to go into problem areas and re-wrap the wires. Wire loom replacement costs are huge warranty items....
I don't live in an area with a rodent problem, but I keep a few hybrids parked outside as DD's. In the fall and winter I have to spray the interior and engine compartments down with peppermint oil to try and keep them away.
