My Running Board becomes a New Mouse Trap

[Doghouse]

I don't drive my truck except on a rare Sunday and at least twice on Mondays.

I washed and waxed it a few weeks ago.

Where I park it is gravel and in the open.

I haven't had it off road since Presidents Day.

So that being said, how'd this mouse get where it is.

When I removed it, it was, well, never mind, but it was apparently there for a while.

Has anyone seen this before?

Looks like he tried to squeeze through and got stuck and sh*t out of luck.

I had a small bird get caught in my grill on the way to Havasu a few years ago. Looks like he was alive for most the trip, there were signs of a struggle.
