Honolulu Zoo Euthanizes Apollo the Lion

HONOLULUL (KHNL) - Apollo, the African lion who lived at the Honolulu Zoo for more than 21 years was euthanized Tuesday morning.

Apollo was nearly 22 years old.  He had kidney failure, arthritis and extreme weakness from muscle atrophy.  His deteriorating health led zoo officials to the decision to end his suffering.

Lions live about 15 years in the wild.  Zoo officials say they can live well into their 20s in captivity because of medical treatment and a healthy diet.
