The Kodkod (Leopardus guigna), also called Guiña, is the smallest cat in the Americas and also has the smallest distribution, being found primarily in central and southern Chile and marginally in adjoining areas of Argentina. In 2002, the IUCN classified the kodkod as Vulnerable as the total effective population size may be fewer than 10,000 mature individuals, with a declining trend due to habitat and prey base loss and persecution, and no subpopulation having an effective population size larger than 1,000 mature breeding individuals.

The Kodkod has a small head, large feet, and a thick tail. An adult weighs 2 to 2.5 kilograms (4.4 to 5.5 lb), with a typical length of 37 to 51 centimetres (15 to 20 in), a short 20 to 25 centimetres (7.9 to 9.8 in) tail, and a shoulder height of about 25 centimetres (9.8 in).

The coat has a base color ranging from brownish-yellow to grey-brown. The body is decorated with dark spots, with a pale underside and a ringed tail. The ears are black with a white spot, while the dark spots on the shoulders and neck almost merge to form a series of dotted streaks. Melanistic kodkods with spotted black coats are quite common.
