Stalking though the thick vegetation of its forest habitat, this secretive predator feeds on a variety of birds, including domestic geese and chickens, and also consumes rodents and small lizards (2) (4). Although it hunts its prey on the ground, the guigna is an excellent climber (2), and will climb trees when escaping the pursuit of a predator or to take temporary shelter in the branches (4).
The guigna is primarily a nocturnal cat, although it can also be active during the day (2) (4), and it spends its periods of rest in dense vegetation, often hidden amongst almost impenetrable bamboo (2).
Male guignas occupy large areas, which overlap the smaller ranges of one or more females (2). Female guignas give birth to litters of one to four young, after a gestation of 72 to 78 days. These small cats are thought to live for up to 11 years (4).
