grizzer – Jun 24, 2008 12:00 AM

Grizzer has been extremely hungry since the prolactin hormone kicked in, but as he sheds his winter coat, we see a lean body type. All that food must be going somewhere, but even at his 115 lb fame, he doesn't show it. The wolves are getting weekly enclosure enrichment programs, ice blocks in the pond stuffed with beaver tails, deer tails and venison bratwurst.
