Ultrasound imaging has shown that one of the giant pandas on loan from China to the Toronto Zoo is pregnant with two possible cubs. The zoo says Er Shun has been shown to have two fetuses in tests done this week. They say Er Shun underwent two non-surgical insemination procedures on May 14, 2015 and sperm was used from the other male panda Da Mao, plus sperm from two other giant pandas based in China.
