Happy birthday, wolf pack! 🐺🐺 This month, Kaska turned 15 and Renner turned nine, and we wanted to celebrate in a BIG way! Watch them explore the biggest birthday card in town, which was made even better by smelly enrichments like cinnamon. Give these great gray wolves a little love in the comments and plan to take a trek to the Cotton Family Wolf Wilderness. #detroitzoo #graywolves #birthday #enrichment
