mouse season

Today the dog hauled his blanket out of his house and tore a lot of it apart, as well.  It was unusual behaviour for him, but I didn't hesitate to scold him.Then, I discovered that there had been a mouse nest.  In his blanket.  There were mouse babies, quite recently born, now dead.  Hence the uncharacteristic destruction.  Gah!  Vermin!  Get it out!  In my house?!  How dare they?Not the brightest mouse in the maze, that one.  No mouse parenting awards.  Let's have babies in the dog's house.  We'll live in the blanket, right underneath the dog! It's warm there.  Not a mensa mouse.
