BOISE -- A sad announcement from Zoo Boise:Nadia, the zoo's Amur leopard, was euthanized Monday.

Zoo officials say Nadia's health has been in decline over the past few days and she did not respond to veterinary care. Two years ago, Nadia was diagnosed with chronic renal failure. The poor prognosis and advanced stage of the disease were deciding factors in euthanizing Nadia.

Nadia s quality of life had declined to the point where euthanasia was the proper thing to do. The Amur leopard has been one of the most popular animals at Zoo Boise. Everyone at the zoo is very saddened by her passing, said Steve Burns, Zoo Boise s Director. It will take several weeks to get the full results of the necropsy.

Nadia was nearly 19 years old. She came to Zoo Boise in 1998. We are told that Amur leopards typically live 10-15 years in the wild and about 18 years in captivity at zoos.

The zoo will work with the Amur leopard Species Survival Plan, and will assess the zoo s current animal collection before making any decisions about getting another leopard.
