Houston Zoo Mourns the Loss of Beloved Jaguar, Tesoro

Tesoro’s animal care team offering a quiet goodbye.

On Friday morning, the Houston Zoo said goodbye to 11-year-old jaguar, Tesoro, after he struggled to recover from a serious leg injury. Six weeks after surgery, Tesoro’s condition took a turn for the worse to the point where medical intervention would no longer improve his quality of life. With Tesoro’s wellbeing as the top priority the Zoo’s veterinary and animal care teams made the difficult decision to humanely euthanize the beloved jaguar.  

Tesoro’s injury was discovered in early May when his animal care team noticed him limping, and radiographs indicated he fractured his elbow, had arthritis and elbow dysplasia. After performing surgery Tesoro’s team remained cautiously optimistic, however his recovery was never guaranteed. Houston Zoo’s five incredible veterinarians, along with its veterinary technicians, clinic staff and animal keepers worked together every day to ensure Tesoro received world-class care. The team conducted routine checkups and monitored his condition, ensuring his comfort. This morning, his care team saw that he needed emergency medical attention. While under anesthesia, the team discovered that he had re-broken his leg and was in renal failure—a condition that occurs when one or both kidneys stop working properly. 

Born in 2014, Tesoro arrived at the Houston Zoo as a young cub in 2015 and quickly captured the hearts of guests, staff, and volunteers with his striking beauty, energetic confidence, and remarkable strength. Over the years, he became a guest favorite and an ambassador for jaguar conservation, inspiring countless visitors. 

Tesoro’s legacy lives on through his offspring, including Tesoro’s seven-month-old cub, Rojo. Through them, Tesoro’s story will continue to inspire future generations of animal lovers and conservationists. 

The Houston Zoo remains committed to honoring Tesoro’s life by continuing its efforts in jaguar conservation through Saving Animals from Extinction (SAFE): Jaguars, a program focused on saving jaguars in Cockscomb Basin Wildlife Sanctuary in Belize. The Zoo provides support to help fund local rangers who patrol the critical habitat, working to reduce illegal activities like poaching.
