Even us big bad bears do from time to time..
This is actually two cubs from different sows who each day found each other to play. The two sows actualy kept their distance from each other but allowed the two large spring cubs to have plenty of time with each other each time they crossed paths.
Mostly they just sat or lied down while the cubs jostled with each other for hours..
Photo was taken on my last trip to Katmai National Park in Alaska.
