T.J., a tiger cub whose mother at the Denver Zoo died when he was only ten weeks old, was raised by the zoo hospital. T.J. gained weight slowly and at first had to be force-fed. Appropriate picture, bar, circle, and line graphs depict T.J.'s weight gain, his father's weight at the same age, and how much meat T.J. ate as he grew, while crisp color photos show the young tiger cub's antics.
