This afternoon I noticed very, very small mouse droppings on the console by the gear shift so I decided to thoroughly inspect the interior of the vehicle.
Upon lifting the rear seat cushions here is what I found:


Obviously a mouse nest. Can anyone tell me where the mouse would have obtained these types of fiber/threads from? The only one that looks familiar is from the yellow firewall insulation.
Maybe the insides of the seats? Under the carpet?
Thanks
