From the Plumpton Park Zoo:
Late yesterday evening, Plumpton Park Zoo had to say good-bye to one of our most beloved animals, “Sis,” our Siberian Tiger. At 17 years of age, Oasis (or Sis as she was known by most) was an elderly tiger. Sis was a favorite at the zoo from the time she arrived 15 years ago.
In the last year, Sis had been engaged in a prolonged fight with lung cancer. Even with the ravages of advanced age and illness upon her, we were continually inspired by Sis’s amazing and sweet temperament. During her battle, we spared no expense in time or medical treatment to make her comfortable. Yesterday, after consultation with Zoo Veterinarians and staff it became clear, that despite those efforts, we could no longer keep her in comfort. The very difficult decision of euthanasia was made to prevent suffering. At 8pm, she passed quietly, surrounded by her loved ones. The entire Zoo staff gathered to be with her in her last moments.
The Plumpton Park Zoo lost a great ambassador for her species, as well as a dear friend. She will be missed by all of us.
Sis lived a long and happy life for a tiger, only 5 days away from her 18th birthday when age and illness claimed her. Medical tests had shown that she was suffering from advanced lung cancer, as well as a spinal condition due to her age and several other minor medical problems.
Our Veterinary Team believed that the care we provided had helped her live another comfortable 6 to 8 months beyond what she would have had without our care. We have taken great solace and comfort in that fact.
A memorial will be erected inside the Zoo to celebrate her life.
