Three Baby Otters Welcomed At Potter Park Zoo In Lansing Some fun news coming out of Lansing's Potter Park Zoo as they announced via a news release that they have welcomed three baby otters to Nkeke and Miles, two of the zoo's North American river otters. Fox 17 reports that the pups were born on February 3rd. Two days later, zookeepers were able to do a physical exam of the pups two of which they believe are female and one that's a male, although they won't officially know for a bit more time has passed because as zoo officials told Fox 17, it's hard to tell gender this young.
