Sumatran tiger Bintang recently underwent a routine wellness exam at Point Defiance Zoo & Aquarium’s healthcare clinic.

While under anesthesia, the veterinary team performed a full physical assessment, including X-rays, ultrasound imaging, bloodwork, IV fluids, updated vaccinations, and a dental evaluation. Head Veterinarian Dr. Karen Wolf said all results were normal and that Bintang is in excellent health.

Detailed exams like these help the veterinary team monitor the overall health of the animals in our care, detect potential issues early, and provide preventive care such as vaccines and dental treatment. Because large cats require anesthesia for these procedures, our zoo veterinarians use the opportunity to perform comprehensive wellness exams, thoroughly evaluating all body systems, minimizing the need for multiple anesthetic events.

“As part of Bintang’s reproductive health assessment, we collected and evaluated a sperm sample while he was under anesthesia,” said Dr. Wolf. “The sample showed healthy-appearing sperm with good motility and concentration, giving us valuable baseline information to support future management decisions.”

With fewer than 400 Sumatran tigers remaining in the wild, accredited zoos collaborate through the Association of Zoos & Aquariums Species Survival Plan® to maintain a healthy, genetically diverse population in human care.

“This type of assessment is an important part of conservation efforts for endangered species like Sumatran tigers,” said Curator of Asian Animals, Telena Welsh. “Reproductive health data helps experts make informed recommendations about future breeding opportunities and long-term population sustainability.”

Point Defiance Zoo currently has a natural breeding recommendation in place for Bintang and fellow tiger Mawar, though there are no plans for artificial insemination at this time.

“Every health assessment helps us better protect this critically endangered species, and we’re hopeful for the future of tigers like Bintang,” said Welsh.
