Strange Critters Moving in to Your House?

There are plenty of crazy creepy things that end up in our houses. I have to say that most of them have given me chills, and I just might have nightmares from some of them. I’ve been thinking about a strange critter nest that my mother found in her car a last month.

My parents were gone visiting my brother for a few days, and during that time a critter moved in. What made it even weirder, was that they didn’t even find it for over a week after they got back. We were on the phone with my mother when she found the nest, and when she described it, all I could think of was a small mouse nest. She emailed me a few pictures of the nest she found, I couldn’t believe how big it was. It was HUGE and not a small little mouse nest either.

It pretty much takes up most of the area under the hood of the car. We think we know what it might be. Any one have any ideas what might live in this nest?
