Germany's Hannover Zoo welcomed this week two new leopard cubs to their zoo family, the Los Angeles Times reported. The two cubs, who are still unnamed, weighed just over a pound after their May 31, 2009, birth. Leopards typically grow to an adult weight of 130 pounds, so these cubs still have some filling in to do. The cubs' mother, Saia, cares to one of the youngsters. (NIGEL TREBLIN/AFP/Getty Images)

After losing her baby son in August 2008 to an intestinal infection, 12-year-old gorilla Gana wandered around the Allwetter Zoo in Muenster, Germany, carrying her dead offspring. Just short of a year later, Gana became a mother again -- and this time the baby was healthy. Gana, shown here nursing her 3-day-old baby, Claudia, earned the world's sympathy for her extended, emotional mourning process. Ilona Zuehlke, a spokeswoman for the zoo, said the birth of Claudia has had a visible effect on the proud mother. "Gana looks very happy," Zuehlke told The Associated Press. (Mark Keppler/AP Photo)

It's a boy. This baby panda was born at the San Diego Zoo on Aug. 5, 2009, and the zoo staff, anxious to leave the newborn alone with its mother, a Chinese-born panda named Bai Yun, did not get to examine the little guy for a month. A baby panda's sex is not obvious when you can only see it from a distance. Following Chinese tradition, the baby will not get a name until he is 100 days old. (Ken Bohn/San Diego Zoo)
