She was 38 years old.
You may know and remember Jia Jia from over a year ago, when the zoo celebrated her 37th birthday with a giant ice cake. According to park officials, her health had been worsening over the past few weeks and she often refused to eat. She struggled with eye cataracts, high blood pressure, and arthritis.
If you were to compare her age in human years, Jia Jia would have been 114 years old—it's easy to understand why her nickname was Grandma Panda. She far surpassed the average life expectancy for a panda in captivity (just over 20 years).
The panda called Ocean Park home for 17 years and was surrounded by the people who cared for her when she was euthanized by park veterinarians around 6 p.m. local time on Sunday. Her mate, An An, is currently 30 years old. He is the second oldest male giant panda in captivity in the world.
