The leopard is the smallest of the four "big cats" in the genus Panthera. Compared to other members of the Felidae, the leopard has relatively short legs and a long body with a large skull. It is similar in appearance to the jaguar, but is smaller and more slightly built. Its fur is marked with rosettes similar to those of the jaguar, but the leopard's rosettes are smaller and more densely packed, and do not usually have central spots as the jaguars do. Both leopards and jaguars that are melanistic are known as black panthers. Of all the big cats the leopards are reported to be "the most numerous and wide spread of the big cats". Its natural design is perfect and is known for its sleekness, smartness and power. It is a predator with tremendous physical power and has immense capability to kill animals which are bigger than itself.

- A leopard doesn't change his spots just because you bring him in from the jungle and try to housebreak him and turn him into a pet. He may learn to sheathe his claws in order to beg a few scraps off the dinner table, and you may teach him to be a beast of burden, but it doesn't pay to forget that he'll al ways be what he was born: a wild animal.
- Leopards on the gable-ends,
Leopards on the painted stair,
Stiff the blazoned shield they bear,
Or and gules, a bend of vair,
Leopards on the gable-ends,
