This House Needs a Mouse — C. Jeffrey Nunnally

This is the high-spirited story of a mouse... disgusted by his caged existence...desperate for a new life. Through a stroke of good timing and some quick thinking, the mouse finds himself free, full of purpose, and exquisitely happy. When his life is turned upside down by an unfortunate chain of events involving traps, rat poison, and one unmotivated cat, this seemingly ordinary mouse must come to grips with his new situation and his true purpose in life.
