Mountain Lion And Cat

Cougars are slender and agile members of the cat family. They are the fourth largest cats and adults stand about 60 to 90 cm (24 to 35 in) tall at the shoulders. Adult males are around 2.4 m (7.9 ft) long nose to tail and females average 2.05 m (6.7 ft), with overall ranges between 1.5 to 2.75 m (4.9 to 9.0 ft) nose to tail suggested for the species in general. Of this length, 63 to 95 cm (25 to 37 in) is comprised by the tail. Males typically weigh 53 to 100 kilograms (115 to 220 pounds), averaging 62 kg (137 lb). Females typically weigh between 29 and 64 kg (64 and 141 lb), averaging 42 kg (93 lb). Cougar size is smallest close to the equator, and larger towards the poles. The largest recorded cougar was shot in Arizona and weighed 125.5 kilograms (276 pounds) after its intensines were removed, indicating that in life it could have weighed nearly 136.2 kilograms (300 pounds). Several male cougars in British Columbia weighed between 86.4 and 95.5 kilograms (190 to 210 pounds).
The head of the cat is round and the ears erect. Its powerful forequarters, neck, and jaw serve to grasp and hold large prey. It has five retractable claws on its forepaws (one a dewclaw) and four on its hind paws. The larger front feet and claws are adaptations to clutching prey.
Cougars can be almost as large as jaguars, but are less muscular and not as powerfully built; where their ranges overlap, the cougar tends to be smaller than average. Besides the jaguar, the cougar is on average larger than all felids outside of the Old World lion and tigers. Despite its size, it is not typically classified among the "big cats", as it cannot roar, lacking the specialized larynx and hyoid apparatus of Panthera. Compared to "big cats", cougars are often silent with minimal communication through vocalizations outside of the mother-offspring relationship. Cougars sometimes voice low-pitched hisses, growls, and purrs, as well as chirps and whistles, many of which are comparable to those of domestic cats. They are well known for their screams, as referenced in some of their common names, although these screams are often misinterpreted to be the calls of other animals.
Cougar coloring is plain (hence the Latin concolor) but can vary greatly between individuals and even between siblings. The coat is typically tawny, but ranges to silvery-grey or reddish, with lighter patches on the under body including the jaws, chin, and throat. Infants are spotted and born with blue eyes and rings on their tails; juveniles are pale, and dark spots remain on their flanks. Despite anecdotes to the contrary, all-black coloring (melanism) has never been documented in cougars. The term "black panther" is used colloquially to refer to melanistic individuals of other species, particularly jaguars and leopards.
