Jenna, a beloved reticulated giraffe born at the Montgomery Zoo who became disabled after a traumatic injury when she was 5, has died, the zoo announced. She was 18.

The zoo made the decision to euthanize Jenna “following an acute worsening of chronic health problems,” the facility said.

“Jenna was a beloved giraffe to our staff and the community,” said Zoo Director Marcia Woodard. “While making compassionate decisions comes with the job, this one was difficult. After realizing her mobility had deteriorated, we had to make the difficult decision to humanely euthanize Jenna so she would not have to endure prolonged suffering. We know our community will be grieving with us during this time.”

Born at the zoo on May 17, 2005, Jenna suffered a traumatic injury to her rear left leg when she was 5 years old. The injury led to a significant change to her feet and posture along with mobility challenges, the zoo said.

Jenna “lived such a full and happy life despite her disability,” the zoo said.

Giraffes in captivity typically have a lifespan of between 20 to 25 years, while giraffes in the wild can live between 10 and 15 years, according to The New York Times.

The Montgomery Zoo encouraged the public to support the facility and welcomed guests to visit Jenna’s sister, Ashley, at the zoo’s giraffe post.
