Okay, suggestions as to what caused this... As my dad and I were putting his plane away, he called me over to look between the front seats and the immediate two backseats - they are back to back. On the floor behind his seat is a fire extinguisher secured to the floor and a bit of space under his seat. In that area, he found a shredded paper towel. He does keep paper towels in the plane, way in the back and it's a roll. This appeared to be one sheet. It's known that mice and rats will run up the landing gear and find a way in, just like Porsches. There were no stains on the carpet, no droppings at all anywhere near this "nest" and the shreddings were as white as can be.

WTF?
