Illegal logging is major threat to their homes too
The cats are almost extinct in their home on the far eastern side of Russia, around Vladivostok.
Now the government and the UK charity named after the leopards - Amur - is raising money to protect them.
Because there are few jobs in the countryside there, people are hunting wild boar and deer living in the forests. That means less food for the big cats.
More worryingly, they are also poaching the tigers and leopards for their precious skin and bones.
But now Russian children are also being taught to look after the environment. Many are now realising that poaching means the animals could disappear altogether.
