Which is the smallest big cat?

The leopard is the smallest of the four “big cats” in the genus Panthera. Once distributed across southern Asia and Africa, from Korea to South Africa, the leopard’s range of distribution has decreased radically over time due to hunting and loss of habitat, and the leopard now chiefly occurs in sub-Saharan Africa.

There are fragmented populations in Pakistan, India, Indochina, Malaysia, and China.

The leopard has relatively short legs and a long body, with a large skull. Physically, it most closely resembles the jaguar, although it is usually smaller and of slighter build. Its fur is marked with rosettes which lack internal spots, unlike those of the jaguar. Leopards that are melanistic, either completely black or very dark in coloration, are one of the big cats known colloquially as black panthers. This isn’t a different species.
