Snowflake the Polar Bear Updates

Published June 29, 2025. Updated March 12, 2026.

Supporting positive welfare at every stage of an animal’s life is integral to the Zoo’s mission. One of our oldest residents is Snowflake, who at age 29 is the second oldest polar bear in an accredited facility in the United States.

Our animal care team carefully monitors her for conditions associated with advanced age to increase her quality of life. Snowflake is currently treated with medication for both a cardiac issue and a chronic skin allergy.

Providing opportunities for choice and exerting control in daily life is also a vital component of her positive welfare. This is why guests may not always see Snowflake when they visit. Her off-exhibit area is divided into several spaces that can be adjusted to offer different environments and enrichment experiences. These comfortable inside areas help keep Snowflake cool in summer and avoid any physical or behavioral strain.

As we navigate the challenges of Snowflake’s aging, we will be sharing our animal care staff’s daily efforts to support her well-being in her golden years. Regular updates will be pulled from actual zoo email communications so that everyone can appreciate the care she is being provided in our staff’s own words. Keep watching for updates!
