HONOLULU (HawaiiNewsNow) - A 24-year-old giraffe at the Honolulu Zoo was put to sleep Thursday to avoid suffering brought on by old age. Yasmin, who came to the Honolulu Zoo from Texas in 1992, was struggling from complications of old age, the City and County of Honolulu said. Certified zoo veterinarians followed American Veterinary Medical Association guidelines to put her to sleep to avoid any further pain. Giraffes have an average life expectancy of 10 to 15 years in the wild and 20 to 25 years in captivity, which makes Yasmin's life an especially long one. Yasmin has given birth to four giraffes in Honolulu.
