Zoo officials say Klondike was having a hard time standing and walking after lying down , as well as a urinary tract infection.

Veterinary staff attempted to treat her symptoms, but there was no improvement in her condition, and her prognosis moving forward looked grim.

According to the zoo, Klondike exceeded the typical life span of for a polar bear.

Klondike was a part of the Philadelphia Zoo community for more than three decades.

The zoo’s remaining polar bear, Coldilocks, is also 34, and is now the oldest polar bear in the United States.

Here is the statement from the zoo.

Philadelphia Zoo is sad to announce that Klondike, our 34-year-old female polar bear, was euthanized this morning due to the recent and substantial decline in her medical condition. Zoo animal care staff confirmed that she had a noticeable deterioration in her health approximately two weeks ago, including difficulty standing and walking after lying down. After a complete physical exam the veterinary team treated her for a urinary tract infection as well as mobility issues. Despite treatment, there was no significant improvement in her condition, and given her advanced age and poor prognosis, zoo staff decided that the best decision would be to humanely euthanize her. At 34 years old, Klondike exceeded the typical lifespan for her species, and was the oldest polar bear in the country. Our remaining polar bear Coldilocks, also 34, now becomes the oldest polar bear in the U.S.

In addition to the joy she brought our staff and guests over three decades here, she has been an important ambassador to wild polar bears, who are increasingly threatened by climate change and resulting shrinkage of polar ice. We hope she has inspired many to make commitments in their daily lives to reduce energy and water use, which will contribute to efforts to slow climate change.
