The common name, kodkod, originated from the Araucanian Indians. Guigna is the common name used in Chile and Argentina (Sunquist and Sunquist, 2002).
Recent genetic analysis suggests that Leopardus guigna is closely related to Leopardus geoffroyi (Sunquist and Sunquist, 2002).
Due to the rare and secretive nature of kodkods, there is little information regarding communication and perception. Like most small cats, kodkods have excellent vision, hearing, and sense of smell. They are likely to use chemical cues in communication as well as vocalizations, body postures, and tactile cues.
Perception Channels: visual ; tactile ; acoustic ; chemical
Kodkod populations are declining, especially in central Chile. They are listed as vulnerable by the IUCN and are on the CITES Appendix II list (Kodkod and Chilean cat, 2009). They are threatened by domestic dogs and hunting by humans, and habitat fragmentation and loss due to deforestation. Their main threat is fragmentation and destruction of their preferred habitat, temperate moist forests (Acosta and Lucherini, 2008). Human sentiment towards kodkods in rural areas is generally negative. Education, awareness, and stricter law enforcement are needed to improve human attitudes towards kodkods and their protection (Silva-Rodgrquez, Ortega-Solis, and Jimenez, 2001). There are laws in place to protect kodkods and other small cats from hunters, but only in some areas and enforcement is generally weak (Lucherini and Merino, 2008). Fortunately, kodkods are relatively tolerant of disturbed habitats, which is reflected in their current conservation status as vulnerable rather than critically endangered.
US Federal List: no special status
CITES: appendix ii
IUCN Red List of Threatened Species: vulnerable
Kodkods have been known to occasionally prey on domestic poultry.
Negative Impacts: crop pest
Kodkods have been hunted for their fur. However, their small body size makes them less popular among hunters (Postanowicz, 2008). In rural areas kodkod pelts are still found displayed as trophies. Kodkods may help to control rodent populations, which decreases rodent depredation on crops and rodent population outbreaks that spread disease (The World Conservation Union, 1996).
Positive Impacts: body parts are source of valuable material; controls pest population
Although more studies are necessary, research suggest kodkods help to control rodent populations (The World Conservation Union, 1996).
Kodkods are carnivorous, eating mainly small rodents, reptiles, birds, and large insects (Kodkod, 2009; Postanowicz, 2008; The World Conservation Union, 1996). Observed prey species include Norwegian rats (Rattus norvegicus), Austral thrushes (Turdus falcklandii), southern lapwings (Vanellus chilensis), chucao tapaculos (Scelorchilus rubecula), huet-huets (Pteroptochos tarnii), geese (Anser anser), chickens (Gallus gallus), and Chiloé lizards (Liolaemus pictus chiloeensis) (Sunquist, and Sunquist, 2002). They sometime prey on domestic poultry, bringing themselves into direct conflict with humans, often resulting in farmers killing kodkods (Postanowicz, 2008).
Animal Foods: birds; mammals; reptiles; insects
Primary Diet: carnivore (Eats terrestrial vertebrates)
Leopardus guigna is also known as the kodkod, guigna, or Chilean cat. It can be found in central and southern Chile, Chiloé Island of Chile, Guaitecas Island of Chile, the Andes Mountains, and western Argentina.
Biogeographic Regions: neotropical (Native )
Kodkods are terrestrial and arboreal, dwelling in moist temperate forests, particularly in coastal regions like the islands of Chile. The types of forest where they are traditionally found include evergreen temperate rainforests, deciduous temperate moist forests, sclerophyllous scrub, and coniferous forests (The World Conservation Union, 1996). Kodkods are somewhat tolerant of disturbance, as they can be found in primary forest and secondary forest and scrub, as well as on the outskirts of cultivated areas (The World Conservation Union, 1996). They are commonly observed in Chilean Valdivian and Araucaria forests. Characteristics of these forest habitats include altitudes between 1,900 and 2,500 meters, complex canopy layers, bamboo, lianas, and epiphytes (Acosta and Luch, 2008). Additionally, kodkods are found in Argentinian moist montane forests, which also have bamboo, lianas, and epiphytes (The World Conservation Union, 1996).
Range elevation: 50 to 2,500 m.

Kodkods can reach 11 years old in the wild.
Typical lifespan
Status: wild: 11 (high) years.
Leopardus guigna is the smallest cat species in the Western Hemisphere, averaging no larger than a typical house cat Felis catus (Postanowicz, 2008). They weigh between 1.5 and 3 kg (Postanowicz, 2008). Kodkods have body lengths from 40 to 52 centimeters, with tail length between 19 and 25 centimeters (Nowak, Kays, and Macdonald, 2005). They have smaller heads and shorter, thicker tails relative to their large feet and claws, which help them to climb trees (Kodkod and Chilean cat, 2009). The main fur color is gray brown or reddish brown, with dark spots, stripes on their tails and dorsal sides, and pale-colored venter and sides (The World Conservation Union, 1996; Postanowicz, 2008). Some kodkods have eyespots on the backs of their ears because of their characteristic black on white fur markings (Postanowicz, 2008). Melanistic, or darker colored, kodkods are not uncommon and their stripes and spots are often detectable in bright light (Sunquist and Sunquist, 2002). They are similar in appearance to Geoffroy's cats (Leopardus geoffroyi) except kodkods have less distinct stripes on their head and shoulder regions and they have thicker tails (Sunquist and Sunquist, 2002).
There are two subspecies: Leopardus guigna tigrillo and Leopardus guigna guigna. Leopardus g. tigrillo is found in the southern Patagonia region and can be identified by its overall paler coat color without spot markings on the feet (The World Conservation Union, 1996). Leopardus g. guigna is found in central Chile and can be recognized by its smaller body size, brighter colors, and spot markings on the feet (The World Conservation Union, 1996).
Range mass: 1.5 to 3 kg.
Average mass: 2.2 kg.
Range length: 40 to 52 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Known predators of kodkods include humans and domestic dogs (Lucherini and Merino, 2008). Kodkods are cryptically colored and secretive, avoiding most predators.
Known Predators:
Anti-predator Adaptations: cryptic
There is minimal information about the mating systems of kodkods because of their rarity. The larger home ranges of males may indicate that they range widely in search of multiple mates.
Kodkods have litter sizes that range between 1 and 4 offspring (Sunquist and Sunquist, 2002). They have a gestation period between 72 to 78 days. Breeding interval and seasonality have not been reported. Sexual maturity is reached at approximately 24 months for both males and females (Postanowicz, 2008).
Breeding interval: Breeding interval has not been reported.
Breeding season: Breeding seasonality has not been reported.
Range number of offspring: 1 to 4.
Range gestation period: 72 to 78 days.
Average age at sexual or reproductive maturity (female): 24 months.
Average age at sexual or reproductive maturity (male): 24 months.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
There is minimal information on parental investment in kodkods. Like other small cats, kodkod females are likely to provide the only parental care. They invest significantly in gestation and lactation and may provide extended care for the young, teaching them to hunt before they become independent.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)
