Mice have eaten quite a lot of the tubular rubber sealing gasket at the
bottom of my rear hatch (regular Vanagon).  I know they can get in some
incredibly narrow openings and I suspect they squeezed into the gap between
the hatch & body but I'm not certain of that.  This was mostly in the desert
areas (e.g., Joshua Tree) of California.  Never actually saw them so I don't
know what kind they were.  //Jack
