Four cats living with their old owner, Joseph, in a rubbish-filled house. Not the best life for four devoted pets, but Shadow and his three house-mates deal with it. However, when Joseph disappears, life is even harder. How can they survive with no humans to rely on? Is it possible to form a friendship with a sworn enemy? Or will old grudges ruin their chances of survival?
