Catboy by Eric Walters

Taylor and his mother have moved from a small northern town to the heart of Toronto. The differences are dramatic as Taylor becomes part of a classroom of kids as diverse as the city itself. While taking a shortcut across a junkyard with his new best friend, Simon, Taylor becomes aware of a colony of wild cats that make the junkyard their home. Assisted by his classmates, teacher and the security guard, Mr. Singh, Taylor takes a special interest in caring for the cats. Suddenly there is an announcement-the junkyard is being redeveloped to become condominiums. Can Taylor and his friends save the cats of the colony from certain death?
