OK, in this one story, I have three shapeshifters, each of which can turn into big cats at will. One turns into a cheetah, one a lion, and one a leopard. In order for the main plot to take place, they have to decide that they'll live civilization behind and go live in their animal forms on a nature preserve. Problem is, everyone I talk to says that they'd never want to do that - and with good reason, because the life of a wild animal is really tough. How do I explain their decision? What possible reasons could you think of for someone to decide to do something like that?
