the clue--a shrew

I asked what the pest guy is doing coming by early January.  He found a reason.  Apparently one pest was moving about.  An adolescent rat?  He thinks it's a shrew.  A shrew?  Thought that was a renaissance rodent Shakespeare wrote about.  No, I'm told.  This is related to the vole, an insect-, berry-, and nut-eating critter. There was no struggle this zero-degree day.  That rat trap (bigger than it looks) could severely hurt your finger.
