Pippi was rescued in spring 2015 and came from the same Conway, S.C.-based facility as Jane. At the time of rescue, she was believed to be a week to 10 days younger than Jane and weighed 2.1 pounds. She weighed 7 pounds on arrival at Mote. Pippi is more shy and calm than Jane, with darker coloring around her face.
