Painter's mouse
A painter's mouse is a little furry troublemaker that gets dropped in the house to keep the cat from ruining the painter's work.
The mouse ran. The cat ran. The painter said, 'At least I don’t have to paint over a cat’s face.'
The painter used the mouse. The cat got distracted. The painter got a perfect wall.
The cat chased the mouse. The painter cussed. The wall got painted. The cat got a new nickname: 'The Painted Pest.'
