Wellington Zoo has put down its red panda Amy after she failed to recover from arthritis and kidney problems.
The zoo said the 15-year-old red panda was diagnosed in November last year and had been receiving treatment from its veterinary team.
However, during a health check today, staff found her condition had worsened and treatment was no longer effective.
The decision was made to euthanise her.
"These decisions are always hard, and it comes down to the animal's welfare and ensuring that we do what is in their best interests," Wellington Zoo chief executive Karen Fifield said.
