Spring cleaning

Ours is a small house, less than 1500 square feet, occupied by two quiet middle-aged adults who do not do much more than work long hours and then come home and read.

So how in the world does it get so dirty?  We cleaned all day Saturday--all day. And never got to the bedrooms.

Where does all this dirt and grit come from?

Oh yeah.

UPDATED: Boscoe on Saturday. See how great he looks, at almost 14? His back legs are wobbly and weak, but his front end keeps smiling.
