 Craig decided right then and there to open his own sanctuary on his parents' small Colorado farm. With few regulations to guide him, he built the animal enclosures himself and scoured biology books for pointers. Did you have any experience with lions and tigers? No, none. Did you have a degree in zoology? No, I was just starting college back then. It was going to be a business degree. And he quickly learned that lions and tigers are no house cats.
