A Sumatran tiger at the Point Defiance Zoo & Aquarium lost his battle with kidney disease and lymphoma this morning.
Veterinarians euthanized Bali, 14 1/2, after more than two years of working to arrest his cancer and slow his chronic kidney disease.
Head veterinarian Dr. Karen Wolf said the efforts gave the 265-pound tiger additional, quality time.
Bali went through chemotherapy and was given many other medications, but became increasingly ill in recent weeks, Wolf said.
“His quality of life was severely compromised,” she said. “He was not eating and became very lethargic.”
The cat far outlived the lifespan of a Sumatran tiger in the wild, which is an estimated 10 to 12 years.
Bali is survived by mate Jaya, and fathered cubs Bima and Mali.
He came to Point Defiance Zoo & Aquarium in 2009 to mate with Jaya, and fathered the two cubs the next year.
Before that, he sired three other cubs at San Francisco zoo.
Point Defiance has four Sumatran tigers now: Jaya, Malosi, Bima and 3-month-old Dumai.
It also has 3-month-old Malayan tiger Berani.
There are only 71 of the critically endangered Sumatran tigers in North American zoos, and an estimated 300 live in the wild.
