ORLANDO, Fla. (CBS4)- After more than 17 years together, Denver’s favorite polar bears will be split up.

Snow is moving to Tucson, Ariz. because she has chronic allergies. Her brother, Klondike, will stay at Sea World in Orlando, Florida.

Zookeepers at the Denver Zoo raised the siblings but they moved to Orlando when they were just one year old.

Other than allergies, Klondike and Snow are happy and healthy polar bears.
