The Geoffroy's Cat is a wild cat. While the species is relatively common in many areas, it is considered to be Near Threatened by IUCN because of concern over land-use changes in the regions where it lives.
Geoffroy's cat is about the size of a domestic cat, averaging 60 centimetres (24 in), with a relatively short, 31 centimetres (12 in), tail. This felid weighs only about 2 to 5 kilograms (4.4 to 11.0 lb), though individuals up to 7.8 kilograms (17 lb) have been reported. In general, those found in the southern part of their range are larger than those from the north, and males are larger than females.
Their fur has numerous black spots, but the background colour varies from region to region: in the north, a brownish-yellow coat is most common; farther south, the coat is grayish. As with most wild cats, the fur of the underbelly is paler, being cream-colored or even white. There are dark bands on the tail and limbs, and similar markings on the cheeks and across the top of the head and neck. The backs of the ears are black, with white spots (ocelli). Melanism is common both in the wild and in captivity.
They prefer open woodland or scrubland habitats with plenty of cover, but are also found in grasslands and marshy areas.
They prey primarily on rodents, hares, small lizards, insects, and occasionally frogs and fish; it is at the top of the food chain in its range.
Geoffroy's cat is nocturnal. Although they are able to climb trees, they rarely do so, except to leave feces to scent mark their territory. Like other small cats, it is a solitary hunter, regularly contacting others of its species only during the mating season. Females maintain territories ranging from 2 to 6 square kilometers (0.77 to 2.32 sq mi), while males have larger ranges, reaching up to 12 square kilometers (4.6 sq mi).
