Breeding

With a Human
Humans and Hewan cannot have children together. They could always adopt, and due to this orphans and homeless children are far less common.

With Another Hewan
Hewan breeding with one another could result in three outcomes. The breed of the mother, the breed of the father, or if the two are from the same family (Felidae and Canidae), say a fox and an arctic fox, they could have a hybrid.
