Well this is a new one for me. I live in North Eastern Oklahoma near Mounds. I have an old chevy 4x4 setting back in the woods. I never drive it because it gets 5mpg and has a 12" lift and is used just for pulling out the other trucks when they get stuck. It also has a massive hole in the floor board. About 1 square foot.. Well anyway it has been setting out there for about a year without being driven and I opened it up today and found dead cactus fragments scattered all over it. They range from 8" to 2" in length. Some are still green and some have obviously dried out. They are under the seat, under the dash, behind the seat, wrapped up in an old jacket, pretty much everywhere. Something had to bring them in there but what? or why? Does this sound like something a rodent might be capable of doing? Im really stumped here.
