Based on the small version of The House Cat, this book is intended as a whole class teaching resource used by teachers to teach reading and writing conventions. It is recommended by the NLS for use in the shared reading session of the reading hour, particularly at Key Stage 1. It tells the story of Tom Cat who lives in a house with two families; he is the House Cat. At the beginning of the story the two households are described, and it is immediately apparent that the two abodes within the house - upstairs and downstairs - provide settings for the House Cat which are very different from each other.
