Flour Power

While the cat's away, the mice will play. . .

 Or in this case, get into the pantry.

 The cat really wasn't away. . . 

 She was in the next room finishing up a cookbook to send out to relatives for a family reunion.

  One little mouse sure can do a lot.

 The cat didn't even want to look at where the mouse had been after he came in covered in flour.

The cat was the one who wanted to say "EEeeekkk!"

This is one thorough mouse.  He's definitely got flour power.
