Thanks to all for your helpful comments. I think the idea of putting scotchbrite or some metal substance will deter the mice from the cabin in the future. I agree with Chris that mice are a serious threat not to be taken lightly. I appreciate the update on the tomcats Charlie from Wefings. If anyone sees my 2003, 22' high-top, low 82 (or so) hrs, fully loaded with ac c-dory for sale on this site in the near future, they will know the reason.
