@#1 ... Airlines usually have strict restrictions involving rodents on board planes in order to prevent electrical wiring being chewed through. ...

I can understand that.

About 18 months ago, I had a $2,000 repair bill because mice in my detached garage chewed through the insulation of a wiring harness in my car.

I first learned of the issue when the "check engine" light on the dashboard lit up. The car still ran, but it was telling me that something was wrong. So I brought it to be serviced.

Long story short (probably too late for that now) ...

The dealer, to assure they had fixed all the damage, had to snake a video cam down through the various channels in the car that the wiring harnesses (yeah, plural) traverse. They showed me the videos of the before (damaged harness due to lack of insulation) and after (replaced wires in the harness).

Needless to say, now I have mouse traps in that detached garage. Trap that have caught seven mice since then.

The attraction of the mice? Warmth in the winter. The garage (even though it is detached) is warmer than the ambiient air. Then the warmth of the car engine and other items in a car (e.g., exhaust system) attracts the mice, who then feed on the insulation of the wires.

The dealer told me that this is not a rare problem they have to repair, it is quite frequent.

So, kudos to SAS for their abrupt, but justified response to this situation.
