Birthdays are very special and when each year is the equivalent of seven human years they don't come along that often either. These animals and their owners really know how to celebrate. Everyone knows a good cake is an essential part of a birthday party!
Jia Jia is both the current record holder for oldest panda in captivity and the oldest panda ever in captivity, stealing away the title from the previous owner who lived to be 36-years-old. Pandas tend to live longer in captivity than in the wild so she's quite old by any panda standards. To celebrate, she was given a cake made of ice and vegetables, but she mainly stuck to chewing on bamboo and posing next to it.
