    Physical description
    This is the second smallest wild cat in South America, with a size similar to that of a domestic cat. This spotted coat has a yellow-gold pelage with dark rosettes arranged mainly on the open side of the body. The rosettes on the back merge into stripes that run from the top of eyes to the base of the tail.

    Habitat and Ecology
    It occurs from northern Costa Rica to Southern Brazil / northern Argentina, occupying a variety of habitats, from those with more open areas to areas with dense forest vegetation. However, it is no where common and populations appear to be localised (de Oliveira et al. 2008).
    As with many other small cats, this species has been poorly studied. Existing data shows that it is a solitary animal, with both diurnal and nocturnal habits and feeds on small rodents, lizards and small birds (Wang 2002).

    Threats and Conservation
    Hunting for its fur and the destruction of forests are the main threats to this species. Populations are severely fragmented and are being reduced severely by habitat conversion to plantations and pasture (de Oliveira et al. 2008). In addition, little is known about the biology of this species, which limits the ability to generate effective conservation strategies. It is classified by the IUCN (International Union for Nature Conservation) as vulnerable and by IBAMA, as threatened with extinction.
