When street musician James Bowen found an injured cat curled up in the hallway of his apartment building, he had no idea how much his life was about to change. James was living hand to mouth on the streets of London, barely making enough money to feed himself, and the last thing he needed was a pet. Yet James couldn't resist helping the strikingly intelligent but very sick animal, whom he named Bob. He slowly nursed Bob back to health and then sent the cat on his way, imagining that he would never see him again. But Bob had other ideas.
