"Trouble" the grizzly bear got his name after he broke into the Anchorage Zoo three times, continually raiding the duck and goose food pellets. After catching and tranquilizing Trouble, Alaska Zoo staff loaded him into the cargo bay of a Northwest Airlines passenger plane headed to Minnesota. Before he could be moved into his new home at the Lake Superior Zoo, veterinarian Dr. Mary Wictor drew blood, gave him a physical, and neutered him. Dr. Wictor said he was in amazingly good health for being a wild animal. However, there were some old injuries to his mouth possibly from a prey animal that fought too hard or a fight with another wild animal. The injuries may explain why Trouble chose to break into the zoo for what looked like an easy meal.
