From the zoo's Facebook:
"Our hearts are heavy with the loss of Shanti, the Sacramento Zoo’s 20-year-old Snow Leopard who was euthanized on Friday, July 12 due to her poor quality of life following traumatic injuries. At 20, Shanti was among the oldest Snow Leopards in the Association of Zoos and Aquariums (AZA) Snow Leopard Species Survival Plan® (SSP).
When keepers arrived at work Sunday, July 7 they noticed that Shanti was injured and unable to move around comfortably. Upon closer examination by the Zoo’s veterinarian it was determined that Shanti had incurred trauma to her back which included damage to her vertebrae. The Zoo’s veterinarian treated Shanti’s injuries and she was started on a course of antibiotics and pain medication. When Shanti’s condition worsened due to further neurological complications and infection, the Zoo’s veterinarians and animal care staff made the difficult decision to euthanize her.
Some of Shanti’s injuries including a bite wound indicate that there had been aggression overnight between her and a companion, a juvenile male Snow Leopard with whom she has lived for the last 7 months. However, it is unclear exactly if and how the bite wound and other traumatic injuries were related.
“Shanti is an icon at the Zoo, an excellent and patient mother and an incredible character. She was well loved and will be missed by keepers and visitors alike,” said Leslie Field, Supervisor of Mammals at the Sacramento Zoo."
