First published in 1961, The Incredible Journey tells the story of three pets: a young Labrador retriever, an old bull terrier, and a Siamese cat. While their owners are away in England, they are being cared for by a family friend at his home in the country. But a miscommunication occurs between the friend and his housekeeper when he goes on a hunting trip, and the animals are left alone for a several hours, with a gnawing instinct that something has gone wrong. They soon set off on a journey to find home, which instinct tells them is to the west.
They travel 400 kilometres across the Northern Ontario wilderness, facing many obstacles along the way: swift-flowing rivers and the rugged landscape; wild animals and unsympathetic humans; starvation, injuries and sheer exhaustion. Separately they would not have survived, but together this disparate group prevails, and they find their way home to the family they love.
