This guy found these 2 grizzly cubs with the dead mother in Alaska . One cub survived and he managed to raise it to maturity. You can see how his family interacted with the bear as it matured. Look at the size he has grown to. The bear must feel he's another pet (notice the honored guest at Thanksgiving dinner) and the humans are his "family". He's housebroken, very gentle and comes and goes as he desires. Can you imagine having something like this as a pet? You certainly wouldn't have to worry about someone breaking into your house if you happened to be gone for a few days would you?
