Brutus, an 800-pound grizzly bear, is Casey Anderson's best friend. Casey -- a naturalist -- and Brutus have been inseparable since Brutus was a two-week-old cub. Casey saved the bear from an overpopulated wildlife park, and raised him with lot of attention, love and respect. Brutus is living in a sanctuary that Casey built so he can freely live a life which a grizzly bear is supposed to live. Being around Brutus is not dangerous because he is comfortable around people, but Casey is still not letting anybody have physical contact with Brutus but himself. He is not afraid that the bear will ever attack him because he knows and can predict his every movement.
