Hunter by Eric Walters

Hunter knows humans are dangerous to himself and the other cats of his colony. He avoids them, as all wild cats should. So when a neighborhood boy starts showing up in Hunter's junkyard to chase away dogs and bring the colony food, Hunter keeps his distance. But a new condo development puts the whole colony in danger, and Hunter soon realizes the only way to save his family is to put his trust in the boy.
The story of Catboy told through very different eyes.
