The Sacramento Zoo has reported the passing of Serai, a female clouded leopard who, along with her companion Rajasi, was pivotal in initiating the species' presence at the facility earlier in 2025. Arriving from the Smithsonian Conservation Biology Institute, the pair had been a significant addition; however, Serai had faced a series of health challenges leading to her death at the age of 14, as confirmed on Friday by zoo officials. According to a CBS News Sacramento report, her lifespan almost matched the upper end of the species' expectancy in captivity, which ranges up to about 17 years.
Concerns about Serai's health were raised in July when zookeepers observed the leopard struggling with balance issues. Following this, in a narrative released by the Sacramento Bee, a mass was detected within her parathyroid gland. Though the mass was surgically removed, a full recovery eluded Serai, and lingering symptoms persisted. Despite the setback, continued efforts were invested in Serai's care, attempting rehabilitation to restore her health.
The decisive moment came on September 29 when, according to Sacramento Zoo officials, a wound to Serai's front leg was found; assessed to be grievously serious. In facing the prospect of amputating the limb, which would have significantly impaired her quality of life, the zoo made the tough decision to euthanize Serai. "Our animal care team and vet team worked around the clock throughout Serai's health journey, pouring an incredible amount of time, energy, and heart into her care," the Sacramento Zoo said in a statement acquired by The Sacramento Bee. They emphasized their responsibility to Serai's quality of life as a guiding factor in their decision-making process.
The beloved big cat had been secluded from public view since the investigation into her symptoms began, as noted by zoo officials. In expressing condolences, they recognized Serai's profound impact, stating, "Serai will be deeply missed by all who knew her and worked with her," as told to CBS News Sacramento. Her passing marks a somber event for both the zookeepers at the Sacramento Zoo and the community that valued her presence.
