The Amur leopard didn't fall for the purring ploy.
There are less than 50 Amur leopards remaining in the world in far Western Russia, in the same fragile region as the Amur tiger. They are classified critically endangered. There are also very few in captivity. The genetic pool is tiny and growing weaker.
Go see this magnificent cat in Binghamton; find a group working for survival of the Amur leopard and consider joining it. Reflect on how small the planet has become.
