Giant panda Kai Kai and Jia Jia celebrated their birthdays Thursday at Singapore’s River Safari, with all the spotlights focusing on whether Jia Jia is pregnant or not.
Female panda Jia Jia turns seven on Thursday while its mate, Kai Kai will soon turn eight on Sept. 14.
They have attempted to mate in April this year, and Jia Jia received artificial insemination as the natural mating didn’t work.
In the past two months, Jia Jia started to show signs of pregnancy, by eating less bamboo, sleeping more, and spending more time in her den and her hormone levels are increasing.
However, it is still uncertain whether Jia Jia is pregnant, as giant pandas commonly display pseudopregnancies and experts worldwide are often not able to determine pandas’ pregnancy status until a late stage.
The panda’s birthdays is marked with a Panda Party Week from Sept. 5 to 13in River Safari, interactive booths are available for visitors to earn more about giant pandas. In addition, children born in 2007 and 2008 can get free entrance in the whole month of September.
Kai Kai and Jia Jia, known as Wu Jie and Hu Bao respectively in China, arrived in the city state on Sept. 6, 2012. They will be staying in Singapore for 10 years.
