When Carries sees Drusilla she has to have her. She had wanted a kitten, but it's love at first sight. Owning a duck is fun, and different, but it's not always easy. When Carrie's family goes on holiday, Drusilla can't go with them, but she can't stay at home either. Where do you leave a duck safely? How can you be sure she's not going to turn into someone's dinner?
