Philadelphia Zoo announced today that Coldilocks, a 37-year-old female polar bear, was euthanized due to a recent serious decline in her health. Zoo animal care staff had become increasingly concerned about Coldilocks, as she began showing worsening changes in her behavior and appetite. Coldilocks had a variety of age related medical issues and as with any aging animal, the veterinary staff worked closely with her caretakers to monitor her quality of life. Making the decision to euthanize an animal is never easy, especially one as beloved as Coldilocks, but after observing her the past week and examining her on Monday morning under anesthesia, they reached a consensus that euthanasia was the most humane option.
Born on December 13, 1980 at Seneca Park Zoo in Rochester, NY, Coldilocks arrived at Philadelphia Zoo on October 6, 1981.
At age 37, Coldilocks well surpassed a typical polar bear lifespan of about 23 years, and was the oldest polar bear in the country at the time of her death.
During her many years in Philadelphia, Coldilocks remained one of the Zoo’s most cherished animals, delighting people of all ages and at the same time inspiring them to care about polar bears and the conservation issues endangering them.
