If your insurance covers rodent damage I would certainly use. Repairs like this can quickly become expensive and the scale of the damage is identified.
My insurance specifically excludes rodent damage. Initially I thought nothing of the exclusion, then last summer I close friend who stores his trailer on his personal ranch had this happened -- net result a 2010 5er was totaled. The repair cost escalated based on how much had to be disassembled in order to make the repairs. His was a unique situation, it was ground squirrels, and they bedded down for the winter in his trailer, had babies and huge stores of nuts were brought in.
I thought about changing insurance to eliminate this exclusion, but then I just decided never to park long term next to a almond orchard.
I doubt your are looking at the scale of damage he had -- but my point is if your insurance convers this claim, make the claim.
