Mrs. Watson works hard doing the family's laundry. She pegs it on the washing line to dry, but the Siamese cats Wishy and Washy have fun playing with the hanging clothes, and soon the washing is dirty and torn. When a passing witch spots the mess and decides to teach the two cats a lesson, they begin to understand the damage they have done, and with the help of the witch's magic, all is set right again. A clever and imaginative tale demonstrating consideration for others, beautifully illustrated by the author.
