This Father's Day weekend, dads can trade some of those half-empty bottles of aftershave for a day of wild fun with the family.

Dads can redeem cologne for free Zoo admission by bringing a new or partially used bottle to the Zoo all Father's Day Weekend along with a paid child or adult ticket.

The cologne is sprayed in their habitats. Dads and their families will watch the animals' reactions to the scents as they teach the animals how to use their instinctual sense of smell.

As many animals perceive the world as much through smell as human do through sight, a spritz of cologne on a tiger-sized toy, a tree, or a path arouses curiosity in the animals to use their skills to investigate their surroundings.

Donated cologne will be used throughout the day all weekend long during Meet the Keeper Series talks highlighting these enrichment activities.
