Amur leopards, Iberian lynxes and South China tigers are among some of the most endangered big cats on the planet as of 2015, says Scientific American. Iriomote cats and Scottish wildcats also rate highly on the list.
Big Cat Rescue also lists 36 other species as vulnerable or endangered. The jaguar, the lion and the snow leopard are also endangered, says the Wildlife Conservation Society.
Deforestation is one of the biggest reasons big cat numbers continue to struggle. Hunters and poachers may also decimate localized groups for money. Often, the fur itself is sold on the black market for exorbitant prices. Certain cultures also believe that big cat body parts, like teeth, bones or entrails, have healing properties. Finally, the illegal pet trade is also a significant source of stress on big cat populations.
