In the Americas there are two primary species of large cats of major size. One is the Jaguar, which can still be found in the Southwestern part of the United States, and as far south as the northern part of Argentina.
The cougar, or the puma, as it is also called, is all over South America, the country of Mexico and in the western half of the United States and the Southwestern part of Canada. The cougar is closely related to the common house cat, only it is a much larger animal.
In North America, there are three other types of big cats in addition to the cougar. They are the Bobcat, the Lynx and the Ocelot.
The bobcat is the most well-known of the other big cats, and it is the only one that is not on the list for endangered species. It is about double the size of the average house cat and it has long legs and a bobbed tail, thus its name. It is a night time animal that hangs out in large cat trees when it does its most hunting, so it is not often seen by humans.
The Lynx is about the same size as the bobcat, but it has more tufts of hair on its ears and feet. The lynx lives in the colder climates of the northern United States and in Canada. It has large feet than the bobcat and thicker hair to protect it from the colder climates.
The Ocelot looks like a miniature leopard as it has all of the markings of a leopard, but it much smaller. They used to be all over the southwestern portions of the US, but are now mostly in Mexico and South America.
These animals are not generally to be feared by humans, due to their mainly nocturnal nature. Except for the mountain lions, they have been known to attack humans, but only rarely.
