Night Safari's white Bengal tiger, 13, euthanised after battle with cancer

A white Bengal tiger at Night Safari was humanely euthanised by the staff on Jul. 1 following a battle with cancer.

In an Instagram post on Jul. 2, Mandai Wildlife Group shared that they made "the difficult decision to let him go peacefully" after exhausting all available treatment options, and following careful consideration of his welfare.

Health challenges

A senior tiger at 13, Pasha had been under long-term veterinary care for several age-related health challenges, including severe osteoarthritis.

It affected his mobility and caused him pain, said Trent Van Zanten, a vet at Mandai Wildlife Group, in a statement.

He was then diagnosed with lymphoma, a progressive form of cancer, earlier in 2026.

Despite receiving palliative care and treatment, Pasha's condition declined in his final days.

"It became clear that his welfare was compromised," Van Zanten said. "He was no longer responding to treatment or able to enjoy a good quality of life."

"Following a comprehensive veterinary assessment, our teams made the difficult decision to humanely euthanise him to prevent further suffering."

In his final moments, Pasha was surrounded by the team who cared for him, offering him comfort and saying their goodbyes.

"Pasha was a much-loved member of our Mandai family and will be deeply missed by all of us," the company said in their post.

A special tiger

Born in human care, Pasha arrived in Singapore from Indonesia’s Batu Secret Zoo together with his sister, Keysa, in 2015.

He did not have any offspring.

The Mandai team will continue to monitor Keysa closely as she adjusts to life without her brother, said Mandai Wildilfe Group curator Anand Kumar in a statement.

He added that the tiger siblings had a strong bond, and were often seen playing together, resting side by side, or rubbing their heads together.

Kumar shared that Pasha was a special tiger who was "quiet and introverted by nature, but with his own unique way of showing affection".

"He would greet us with soft chuffs in the morning, just like a cat’s purr, or rub against the mesh whenever we approached his den...

Pasha also had a great love for his enrichment toys, especially his boomer balls, which he would guard closely."

The Mandai team thanked Pasha for the "unforgettable memories" he brought to many.
