Animal novels usually describe the lives and adventures of animals and reflect certain aspects of human society through their perspectives, such as human nature, morality, friendship, love, and so on. Animal novels often use symbolism to suggest a profound theme and meaning through the behavior and characteristics of animals. For example, the death of a wolf might trigger a series of plot changes, reflecting the deep thinking and discussion of human beings about death and life. In addition to describing the lives and adventures of animals, animal novels also involve some profound philosophical and moral issues such as the nature of human beings, freedom and responsibility, etc. The discussion of these questions will help readers think more deeply about the relationship between human society and animals, as well as the mutual influence between them.
