A more thorough explanation:

Sauvagine means a wild animal or the wild nature of an animal.

• The sauvagine of the lion was evident as it roared fiercely in the jungle.
• The sauvagine of the wolf made it difficult for humans to domesticate them.

These examples show how sauvagine refers to the wildness or untamed nature of animals. Lions and wolves are both known for their ferocity and independence, which are characteristics of their sauvagine.
