When Brutus isn't hanging out with Casey, he spends time with other bears at the Montana Grizzly Encounter Rescue and Education Sanctuary—and he even has a girlfriend. "Her name's Shina. She's kind of a tomboy girl," Casey says. "She's a third of his size, but she still pins him down on the grass and kind of shows him that she's the boss. But he loves it."

Bears have a sense of smell stronger than a bloodhound—and Casey says some of the bears get jealous of Brutus if they smell Casey's scent on his fur. "They give him the cold shoulder," Casey says. "Then they realize it's just Brutus, and they're buddies again."
