Brutus is living in a sanctuary that Casey built so he can freely live like 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 predicts his every move.
Favorite things that Brutus likes to do is to sleep, play with other grizzly bears, eat marshmallows and Twinkies, and get attention from people, especially when he “flirts” with women. He is really comic and intelligent, and will always do something silly to make everybody laugh.
Casey and Brutus are actually having their own show on National Geographics that’s called “Expedition Grizzly”. There are several other people that have wild animals as pets, like a hyena or a baboon.
