My niece bought her five-year-old daughter Ruthie a hamster.  One day he escaped from his cage. The family turned the house upside-down and finally found him. Several weeks later, while Ruthie was at school, he disappeared again.

My niece searched frantically but never found the critter.  Hoping to make  the loss less painful for Ruthie, my niece took the cage out of her room.

When Ruthie came home from school that afternoon, she climbed into her  mother's lap. "We have a serious problem," she announced. "Not only is my hamster gone again, but this time he took his cage."
