While not everyone has a pet lion in their house like actress Melanie Griffith did growing up, some families have adopted or taken in wild animals as part of the family.

The practice is not recommended and is actually illegal in many U.S. states. But that doesn't stop these animals from thinking they are just another member of the family.
