The ocelot (Leopardus pardalis) is a medium-sized spotted wild cat that reaches 40–50 cm (16–20 in) at the shoulders and weighs between 7 and 15.5 kg (15 and 34 lb) on average. It is native to the southwestern United States, Mexico, Central  and South America, and the Caribbean  islands of Trinidad and Margarita. Carl Linnaeus scientifically described it in 1758. Two subspecies are recognized.

The serval (Leptailurus serval) is a wild small cat native to Africa. It is widespread in sub-Saharan countries, where it inhabits grasslands, wetlands, moorlands and bamboo thickets. Across its range, it occurs in protected areas, and hunting it is either prohibited or regulated in range countries.

The cougar (Puma concolor) (/ˈkuːɡər/, KOO-gər), also called puma, mountain lion, catamount, and panther, is a large small cat  native to the Americas. It inhabits North, Central and South America, making it the most widely distributed wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread in the world. Its range spans Yukon, British Columbia and Alberta in Canada, the Rocky Mountains  and areas in the western United States. Further south, its range extends through Mexico to the Amazon rainforest and the southern Andes Mountains in Patagonia. It is an adaptable generalist species, occurring in most American habitat types. It prefers habitats with dense underbrush and rocky areas for stalking but also lives in open areas.

The fishing cat (Prionailurus viverrinus) is a medium-sized wild cat of South and Southeast Asia. It has a deep yellowish-grey fur with black lines and spots. Adults have a head-to-body length of 57 to 78 cm (22 to 31 in), with a 20 to 30 cm (8 to 12 in) long tail. Males are larger than females, weighing 8 to 17 kg (18 to 37 lb), while females average 5 to 9 kg (11 to 20 lb). It lives mostly in the vicinity of wetlands, along rivers, streams, oxbow lakes, in swamps  and mangroves where it preys mostly on fish. Other prey items include birds, insects, small rodents, molluscs, reptiles including snakes, amphibians and carrion of cattle. The fishing cat is thought to be primarily nocturnal. It is a good swimmer and can swim long distances, even underwater.

The European wildcat (Felis silvestris) is a small wildcat species native to continental Europe, Great Britain, Ireland, Turkey and the Caucasus. Its fur is brownish to grey with stripes on the forehead and on the sides and has a bushy tail with a black tip. It reaches a head-to-body length of up to 65 cm (26 in) with a 34.5 cm (13.6 in) long tail, and weighs up to 7.5 kg (17 lb).

Suinae is a subfamily of artiodactyl  mammals that includes several of the extant members of Suidae and their closest relatives – the domestic pig and related species, such as babirusas. Several extinct species within the Suidae are classified in subfamilies other than Suinae. However, the classification of the extinct members of the Suoidea – the larger group that includes the Suidae, the peccary family (Tayassuidae), and related extinct species – is controversial, and different classifications vary in the number of subfamilies within Suidae and their contents.[1] Some classifications, such as the one proposed by paleontologist Jan van der Made in 2010, even exclude from Suinae some extant taxa of Suidae, placing these excluded taxa in other subfamilies.[2]

Procyonidae (/ˌproʊsiːˈɒnɪdiː/ PROH-see-ON-i-dee)[1] is a New World family of the order Carnivora.[2] It includes the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous.

Viverridae is a family of small to medium-sized feliform mammals, comprising 14 genera with 33 species. This family was named and first described by John Edward Gray in 1821.[3] Viverrids occur all over Africa, in southern Europe, and in South  and Southeast Asia on both sides of the Wallace Line.[4]

The Mustelidae (/mʌˈstɛlɪdiː/;[2] from Latin mustela, weasel) are a diverse family of carnivoran mammals, including weasels, badgers, otters, polecats, martens, grisons, and wolverines. Otherwise known as mustelids (/ˈmʌstɪlɪdz/[3]), they form the largest family in the suborder Caniformia  of the order Carnivora with about 66 to 70 species in nine subfamilies.[4]

Leporidae (/ləˈpɔːrɪdiː, -daɪ/) is the family  of rabbits and hares (Lepus), containing over 70 species of extant mammals in all. Together with the pikas, the Leporidae constitute the mammalian order Lagomorpha. Leporidae differ from pikas in that they have short, furry tails and elongated ears and hind legs.
