Giovanna, a female polar bear about the same age as Knut, went to Berlin from Munich's Hellabrunn Animal Garden in September 2009. She shared Knut's enclosure for a short time while her regular home had repairs. Her arrival interested people from all over the world, because many sources thought the two bears (although they were sexually immature) would soon be "dating". However, in March 2010, the German chapter of People for the Ethical Treatment of Animals (PETA) called for Giovanna to stay somewhere else. Knut and Giovanna share a grandfather, and PETA spokesperson Frank Albrecht thought the same person who had claimed that Knut should be killed would threaten the German polar bear population if they might breed. The Berlin Zoo did not respond, but noted that Giovanna's stay in Berlin was only for a short time. In August 2010, Giovanna was moved back to Munich after repairs to her enclosure were finished.
