Me too myronman. What a faked up mess that was.
That looked more like a papa bear than a mama and he'd have eaten that cub faster than the cat. They do so regularly out here. Not just cubs either. One of my first years here in Bristol Bay, the salmon run was late at Brooks falls in Katmai. One big hungry bear came out in front of the observation platform, looked around for fish then sank his teeth into the backbone of a smaller bear and proceeded to eat it on the spot while it was dying. Really horrified many of the onlookers and caused the Park Service to close the area for a while.
If that was really a mama bear it wouldn't have stood there wagging its head. I've seen mama bears with cubs charge much larger male bears and really work them over. A friend tho found where mama lost the deal and both mama and cubs were lunch.
