In late 2011, they were introduced together for the first time after previously being separated by wire mesh for breeding. As when they first arrived they were in the same exhibit until Fu Ni reach sexual maturity. Whenever she began her
oestrus cycle, Fu Ni climbed her tree in the enclosure. She experienced several pseudopregnancies, which were difficult to distinguish from actual pregnancies as her blood tests, chemical signals, and behavior would all indicate she is pregnant. Giant pandas have a short annual window to breed, often around 2472 hours. In 2019, Prime Minister
Scott Morrison criticized
Labor's pledge to fund Wang Wang and Fu Ni for five more years, saying that
Queensland floods should be more of a priority. On 24 November 2019, the
Government of South Australia signed a new agreement with China to fund the pandas for five more years, after the initial ten-year deal had expired and the pandas were set to return to China. There have been five previous unsuccessful attempts to get the pair to mate. There were also four or more attempts to
artificially inseminate Fu Ni, including three procedures in 2017 and another that was planned in late 2022. Adelaide Zoo confirmed that Fu Ni had undergone either a "pseudopregnancy or a loss" in February 2023. Wang Wang and Fu Ni returned to China following the expiration of their contract with
Adelaide Zoo in November 2024. They were replaced by pandas Xing Qiu and Yi Lan, as a result of a new deal between
Australia and
China. == Exhibit ==
