It's Mog's Birthday and everyone is excited to celebrate! Everyone except Mog. Mog doesn't like birthdays or parties, and she especially doesn't like them both together. But will she change her mind when it's her own special day? HarperCollins created this special birthday story in collaboration with Judith Kerr, using a selection of pictures from across fifty years of illustrating Mog to bring this delightful story to life. Join us and celebrate fifty years of a really remarkable cat! The classic picture book story has never been out of print since it was first published more than fifty years ago, and Mog has been delighting children all over the world ever since with her funny and warm-hearted escapades. Her stories are the perfect gifts for boys, girls and families everywhere.
