After a suffering from complication from a leg injury, the Zoo had to make a difficult decision.
HOUSTON — The Houston Zoo announced the loss of Tesoro, an 11-year-old jaguar, who was humanely euthanized Friday morning after health complications from a leg injury.
Tesoro, a guest favorite since his arrival as a cub in 2015, underwent surgery earlier this month to repair a fractured elbow.
His care team discovered the injury in early May after noticing he was limping. Radiographs confirmed a fractured elbow, along with arthritis and elbow dysplasia. Though the surgery initially offered hope, his recovery was uncertain from the start.
Throughout his treatment, the zoo’s five veterinarians, along with veterinary technicians, clinic staff and animal keepers, worked together to provide what the Zoo described as “world-class care.” This included daily checkups and continuous monitoring to ensure Tesoro’s comfort.
Despite the team’s best efforts, “Tesoro’s condition took a turn for the worse to the point where medical intervention would no longer improve his quality of life,” the zoo said in a news release.
Tesoro’s condition worsened Friday morning when he required emergency medical attention. While under anesthesia, the veterinary team discovered he had re-broken the leg and was in renal failure — a life-threatening condition in which the kidneys stop functioning properly.
This rapid decline in health led the team to make the difficult decision to humanly euthanized the jaguar. As they mourn his death, his memory lives strong in the Zoo history.
Born in 2014, Tesoro quickly became a standout at the zoo for his “striking beauty, energetic confidence, and remarkable strength.” He played a key role in educating visitors about wildlife conservation and inspired many through his presence.
Tesoro’s legacy lives on through his 7-month-old cub, Rojo.
“Through them, Tesoro’s story will continue to inspire future generations of animal lovers and conservationists,” the zoo said.
In Tesoro’s honor, the Houston Zoo reaffirmed its commitment to jaguar conservation through its partnership with Saving Animals From Extinction (SAFE): Jaguars. The program supports local rangers in the Cockscomb Basin Wildlife Sanctuary in Belize, working to reduce threats such as poaching in critical jaguar habitats.
The zoo emphasized that Tesoro will be remembered not only for his role at the zoo but also for the impact he made on wildlife education and conservation efforts.
