Leopard is an Asian and African mammal. Leopard is the most versatile, crazy, furious, and big cat. Poaching, trophy hunting, and the demand for their parts threaten this specie. 40% population of leopards in Africa and 50% population of leopards in Asia is declined. So, there is a need for transboundary collaboration to conserve the leopards. So, International Leopard Day is celebrated on May 3rd every year to stand out for this specie.
