 In October 1991 , a <unk> named Timmy ( 1959 – 2011 ) was taken away from Kate , his infertile companion at the Cleveland <unk> Zoo , in the hopes of breeding lowland gorillas and introducing new genes into the captive gorilla gene pool . This forced separation led to protests from animal rights activists who expressed concerns about the potential consequences of emotional trauma on the two gorillas . The Association of <unk> and <unk> Species Survival Plan sent Timmy to the Bronx Zoo where he joined Pattycake and other females .
