Posted by Gigi Allianic, Communications That's a face we will never forget. Rest easy, Junior, thank you for letting us love you and inspiring millions to save jaguar habitat. Photo by Dennis Dow/Woodland Park Zoo. Jaguar Cove won't be the same without the presence of our favorite male jaguar, Junior. The geriatric cat had been off view, living behind the scenes where keepers could keep a close watch on him (spoil him) since late in 2017. Junior was humanely euthanized on May 31 due to a major decline in health and quality of life. Junior was 20 years old. The life expectancy of jaguars in zoos is 18 years. The big cats live longer in zoos than in their natural range because of the evolving field of zoo medicine, including improved husbandry and management techniques, excellent animal care, better nutrition, increased medical knowledge, and diagnostic and therapeutic techniques. Sweet cat naps on his favorite hot rock made Junior a happy boy. Photo by Ry
