Pusskin has always lived with his loving owner, eleven-year-old Lottie. The bond between them is unbreakable, or so they both thought. But when the bird and insect populations are depleted, cats are made a scapegoat. Keen to protect his cat friends on the cul-de-sac, Pusskin sets off on a journey that will take them to a hidden island at the furthest reaches of the country. When Lottie tries to bring him home, she soon comes to realise that for Pusskin to have any chance of survival, she'll have to let him go. Could this be their final goodbye?
