In March 2010, Potter Park Zoo artificially inseminated a female snow leopard, believed to be the world first successful procedure without surgery or anesthesia. The zoo's 11-year-old female, "Serena", was matched with "Kaz", a male from the Grand Rapids John Ball Zoo. Potter Park's 28-year-old mandrill, "Gladys", died in April 2010. The primate first arrived at the zoo in 1989. In August 2010, Potter Park Zoo became one of 19 international locations to be accredited with a postdoctoral veterinary residency program by the American College of Zoological Medicine. A expanded Eurasian eagle-owl exhibit reopened in September. A mandrill was born at the zoo in November 2010, bringing the zoo's total to four. In December 2010, the zoo acquired a second snow leopard, "Ramir", a 13-year-old from the Sacramento Zoo, as part of the Association of Zoos and Aquariums Species Survival Plan (But "Ramir" died at least a year later). The same month, a 15-year-old Bactrian camel, "Newton", had to be euthanized due to arthritis.
