Snow Leopards are generally smaller then true leopard's, and their tails are much longer, and their heads are rounded more then a regular leopard. The biggest difference is that the females are bigger then the males usually. Snow Leopards are completely adapted to moving in a montane environment. Their feet are like large snowshoes and their legs are made for mostly jumping and running. The Snow Leopard has very large nasal cavities to enable them to efficiently breathe in the thin oxygen, cold and dry air of high altitudes. The Snow Leopard has a round pupil differing them from other types of domestic cats.
