In 'Harold's Worst Nightmare', a pampered adult cat lives a wonderful life at the centre of his owners' worlds. When a new kitten arrives, Harold's world is turned upside down. Can Harold and Muffin learn to get along?

This fun story features two adorable pets as they learn to love each other and share their home. You can use this story to help children to understand their sibling relationships or simply how to get along with another person who's different from them. Whether children have a big brother or sister or a new baby sibling, they'll relate to Harold's frustrations and hopefully be inspired by his ability to get along with Muffin in the end.

The story also presents differences in a positive light - where Harold is older and more relaxed, Muffin is young and full of life. At first, this seems like a problem for the two of them, but they soon find out that they can learn a lot from each other. This helps children to learn that we all have our differences and individual personalities, but this is what makes us unique!
