In the last week, we have witnessed a significant increase in social behavior between Grizzer and Denali.  Denali seems to be the instigator of the interactions, either spring up in a playbow towards Grizzer, doing a foreleg stab to get Grizzer to interact or just standing near him with his tail wagging over his back.  This is the pre-retirement Denali that we know so well and it has taken nearly a month of retirement for him to return to his normal behavior.  These interactions are not only good for their physical health, but it definitely is helping Grizzer’s cognitive abilities as well.  We hope the behaviors continue as the winter advances.
