What is the main conflict in Whittington by Alan Armstrong?

This novel for young people entwines two contemporary plot lines with a retelling of a classic fable - the story of Dick Whittington and his remarkable cat, as told by a cat who is, in many ways, remarkable himself. As all three plot lines explore issues relating to the power of courage to overcome difficulties, the book also explores the nature and value of friendship, compassion, and interdependence.
