You walk past all of the exhibits and go towards a large domed building at the back of the Zoo. A few minutes later, you end up outside the front doors of the Zoo’s Veterinarian Center. With an excited breath you step though the sliding glass doors and head to the front desk. A busty cheetah woman gives you a smile as you present to her a little black plastic card. “Good morning Mike, who are you volunteering for today?” She cheerfully asks.
