In addition to its unique appearance, the jaguarundi differs from other small New World cats in many aspects of its biology and behaviour. Individuals travel widely in unusually large home ranges and are more terrestrial than many other species, though are also agile climbers (2) (3) (6) (7). The jaguarundi is also much more diurnal than most cats (3) (10) (11). The diet consists mainly of small mammals, birds and reptiles, as well as occasional amphibians, fish and larger mammals (2) (3) (4) (6). Arthropods and some fruit may also be taken (7) (10). The jaguarundi has been observed to jump up to two metres off the ground to swat at birds in the air (6). The breeding behaviour of the jaguarundi is less well known (6). It is believed to live either alone or in pairs (2) (3) (7), and may breed year-round in the tropics, although one or two distinct breeding seasons have been suggested for northern parts of the range (3) (7). The female gives birth to between one and four young after a gestation period of 70 to 75 days (3) (6) (8). The young are born in a den, typically located in a dense thicket, hollow tree, fallen log, or thick grassy clump (6) (7). Like the adult, the young usually lack spots, although some report the newborns to be dark-spotted (2) (4) (6). Young jaguarundis leave the den after about 28 days, reaching sexual maturity at around two to three years, and living for up to 15 years (3) (7) (8).
