Behavior

provided by Animal Diversity Web

Leopardus pardalis has keen senses of smell and vision. It uses its sense of smell to locate, track, and approach prey as well as to determine territorial boundaries. They have acute binocular vision that is well-developed for hunting at night. Leopardus pardalis communicates with conspecifics using chemical signals to demarcate territorial boundaries and vocalizations (e.g., mews and yowls) to attract and communicate with potential mates.

Communication Channels: tactile ; acoustic ; chemical

Conservation Status

provided by Animal Diversity Web

Due to their abundance and broad distribution, ocelots are list as a species of "least concern" according to the IUCN Red List of Threatened Species. Major threats to their persistence include habitat loss and fragmentation, illegal trade as pets and pelts, and retaliatory killings by poultry farmers. Despite this, ocelots have made a strong recovery and it was estimated that there were between 1.5 and 3 million ocelots living in 1996.

Due to their popularity in Western fur trade, ocelots were nearly extinct by the mid 1980's. Concern over their potential extinction contributed to the formation of the 1975 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The selling of ocelot fur significantly decreased in the 1980's and is no longer considered a threat to their survival.

Once found as far east as Louisiana and Arkansas and now found only in southernmost Texas, Leopardus pardalis albescens is the only subspecies that is classified as endangered. This subspecies' declining numbers are likely the result of habitat loss, which is forcing individuals to have larger home ranges in order to support their daily prey requirements. However, larger home ranges may decrease mating opportunities.

US Federal List: endangered

CITES: appendix i

State of Michigan List: no special status

IUCN Red List of Threatened Species: least concern

Benefits

provided by Animal Diversity Web

From the early 1960's to the mid 1980's, there was high demand for spotted-cat furs in Western society. During this time, a coat made of ocelot fur could sell for $40,000 (U.S.) in western Germany. Ocelots were also popular as exotic pets, costing as much as $800 per individual. After the 1975 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the international trade of ocelots and their by-products (e.g., fur) became illegal in most countries. However, one can still buy such items at the Managua International Airport in Nicaragua or illegally on the black market.

Ocelots may be beneficial to humans by controlling rodent populations that could be considered agricultural pests.

Trophic Strategy

provided by Animal Diversity Web

Ocelots are highly skilled hunters, tracking prey by odor trails, and have an average of 0.9 prey captures per kilometer traveled. Once a prey item is captured, they eat at the kill site and cover the remains when they are finished. Similar to other felids, ocelots are well-adapted to their carnivorous diet, shearing ingested tissue from carcasses with their carnassials, while depending on strong digestive enzymes to help break down ingested proteins.

The diet of ocelots consists of 65 to 66% small rodents, 12 to 18% reptiles, 6 to 10% medium-sized mammals, 4 to 11% birds, and 2 to 7% crustaceans and fish. Their primary prey consists of nocturnal species, including cane mice (Zygodontomys), spiny rats (Echimyidae), common agoutis (Dasyprocta), opossums (Didelphimorphia), and armadillos (Cingulata). Although most prey weighs less than 1 to 3% of their body weight, ocelots also take larger prey, including lesser anteaters (Tamandua tetradactyla), red brocket deer Mazama americana, squirrel monkeys (Saimiri sciureus), and land tortoises (Testudinidae).

Animal Foods: birds; mammals; reptiles; fish; mollusks; aquatic crustaceans

Morphology

provided by Animal Diversity Web

Ocelots are the largest member of the genus Leopardus. They weigh between 8.5 and 16 kg, are between 65 and 97 cm long, and males are considerably larger than females. Their pelage is shorter and less soft and thick than their close relative, the margay (Leopardus wiedii). Their ventral pelage is white and their dorsal pelage ranges from off-white to tawny-yellow to reddish-gray. Pelage coloration varies with habitat, as ocelots from arid scrub regions have grayer coats than those found in tropical forests. Entirely black individuals have been seen but are rare. Usually, ocelots have dark streaks, blotches, or rosettes arranged in small clusters around dark-colored areas that tend to run in parallel, horizontal chains. Rosettes and blotches are bordered with black and have a lighter-colored center. Ocelots have two black stripes on their cheeks, black ears with a central yellow spot, and one or two black transverse bars on the insides of the legs. Facial patterns are very distinct, permitting easy recognition of individuals. Their long tail is typically ringed, but may only be marked with dark bars on the dorsal surface. Relative to body-size, they have large paws, which is why their Spanish name is "manigordo", meaning big feet. Additionally, their fore paws are broader than their hind paws. Like other members of the suborder Feliformia, ocelots lack a third molar, have an absent or reduced postglenoid foramen at the base of the skulls, and an anterior palatine canal that passes through the maxilla. They have a concave muzzle and the dental formula is 3/3, 1/1, 3/2, 1/1 for a total of 30 teeth. Their basal metabolic rate is approximately 0.298 cm^3 oxygen/hour.

Range mass: 8.5 to 16 kg.

Range length: 65 to 97 cm.

Average basal metabolic rate: .298 cm3.O2/g/hr.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: male larger

Average basal metabolic rate: 17.368 W.

Associations

provided by Animal Diversity Web

Although predators themselves, ocelots occasionally become the prey of harpy eagles (Harpia harpyja), pumas (Puma concolor), jaguars (Panthera onca), and anacondas (Eunectes murinus). Many of the characteristics that make them great predators may be useful as antipredator defense mechanisms (e.g., camouflage, keen senses, etc.).

Reproduction

provided by Animal Diversity Web

Ocelots are solitary and polygynous, with a single male home range overlapping those of several females. During estrus, females attract potential mates by making loud yowls, similar to those made by domestic cats (Felis catus). After mating pairs are formed, ocelots copulate between 5 and 10 times daily. The likelihood of conception per estrus, which lasts approximately 5 days, is 0.6.

Mating System: polygynous

Ocelots are year-round breeders in the tropics, but autumn and winter birthing peaks reportedly occur in the northern parts of their range (e.g., Mexico and Texas). Estrus lasts 4.63 days on average, and their estrus cycle lasts 25.11 days on average. Once pregnant, females create a den in thick brush where parturition occurs. Gestation lasts 79 to 85 days, and litter sizes range from 1 to 3 kittens, with an average of 1.63 kittens/litter. Young weigh between 200 and 340 g at birth. Females are thought to have 1 litter every 2 years.

Ocelots are weaned by 6 weeks old and reach adult size at about 8 to 10 months old. Females reach sexual maturity at 18 to 22 months old and may breed until they are 13 years old. Males may become sexually mature as early as 15 months; however, spermatogenesis typically begins around 30 months. Evidence suggests that sexual maturation in males is related to territory acquisition.

Breeding interval: Ocelots typically have one to two young every two years.

Range number of offspring: 1 to 3.

Average number of offspring: 1.63.

Range gestation period: 79 to 85 days.

Average weaning age: 6 weeks.

Average time to independence: 12 months.

Range age at sexual or reproductive maturity (female): 18 to 22 months.

Range age at sexual or reproductive maturity (male): 15 (low) months.

Average age at sexual or reproductive maturity (male): 30 months.

Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous

Average birth mass: 255.5 g.

Average number of offspring: 2.

Females alone provide parental care to their young. Juvenile ocelots are weaned by 6 weeks old and begin to observe their mother during hunts a few months after birth. They are independent at approximately 1 year, but may be tolerated in their mother's home range until about 2 years old. After dispersing, juveniles must find their own territories.

Parental Investment: altricial ; female parental care ; pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)

Ocelots live in super densities on Barro Colorado Island

provided by EOL authors

Report on a study assessing demography of ocelots on Barro Colorado Island, with scientists hypothesizing as to the causes of these unsually high numbers.

Ocelot

provided by wikipedia EN

The ocelot (Leopardus pardalis) is a medium-sized spotted wild cat that reaches 40–50 cm (15.7–19.7 in) at the shoulders and weighs between 7 and 15.5 kg (15.4 and 34.2 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 ocelot is efficient at climbing, leaping and swimming. It prefers areas close to water sources with dense vegetation cover and high prey availability. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. It is typically active during twilight and at night and tends to be solitary and territorial. Both sexes become sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically. After a gestation period of two to three months the female gives birth to a litter of one to three kittens. They stay with their mother for up to two years, after which they leave to establish their own home ranges.

The ocelot is listed as Least Concern on the IUCN Red List, and is threatened by habitat destruction, hunting, and traffic accidents. While its range is very large, various populations are decreasing in many parts of its range. The association of the ocelot with humans dates back to the Aztec and Incan civilizations; it has occasionally been kept as a pet.

Etymology

The name "ocelot" comes from the Nahuatl word ōcēlōtl (pronounced [oːˈseːloːt͡ɬ]), which generally refers to the jaguar, rather than the ocelot.[3][4][5] Another possible origin for the name is the Latin ocellatus ("having little eyes" or "marked with eye-like spots"), in reference to the cat's spotted coat.[6]

Other vernacular names for the ocelot include cunaguaro (Venezuela), gato onza (Argentina), gato tigre (Panama), heitigrikati (Suriname), jaguatirica, maracaja (Brazil), manigordo (Costa Rica, Panama and Venezuela), mathuntori, ocelote, onsa, pumillo, tiger cat (Belize), tigrecillo (Bolivia) and tigrillo (Colombia, Ecuador, Guatemala, and Peru).[2][7]

Taxonomy

Felis pardalis was the scientific name proposed for the ocelot by Carl Linnaeus in 1758.[8] The genus Leopardus was proposed by John Edward Gray in 1842 for several spotted cat skins in the collection of the Natural History Museum, London.[9][10]

Several ocelot specimens were described in the nineteenth and twentieth centuries, including:[2][11]

Subspecies

In 1919, Allen reviewed the specimens described until 1914, placed them into the genus Leopardus and recognized nine subspecies as valid taxa based on the colors and spot patterns of skins.[10] In 1941, Pocock reviewed dozens of ocelot skins in the collection of the Natural History Museum and regrouped them to nine different subspecies, also based on their colors and spots.[22] Later authors recognized 10 subspecies as valid.[23][24][11]

In 1998, results of a mtDNA control region analysis of ocelot samples indicated that four major ocelot groups exist, one each in Central America, northwestern South America, northeastern South America and southern South America south of the Amazon River.[25] A 2010 study of morphological features noted significant differences in the size and color of the Central and South American populations, suggesting they could be separate species.[26] In 2013, a study of craniometric variation and microsatellite diversity in ocelots throughout the range recognized three subspecies: L. p. albescens from the Texas–Mexico border, L. p. pardis from Central America and L. p. pseudopardalis from South America, though L. p. mitis may comprise the ocelot population in the southern part of South America.[27]

In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group noted that up to four subspecies can be identified, but recognized only two as valid taxa. These two taxa differ in morphological features and are geographically separated by the Andes:[28]

  • L. p. pardalis has a greyish fur. Its range extends from Texas and Arizona to Costa Rica.
  • L. p. mitis has a more yellowish fur and is larger than pardalis. It occurs in South America as far south as northern Argentina.

Phylogeny

Results of a phylogenetic study indicate that the Leopardus lineage genetically diverged from the Felidae around 8 million years ago (mya). The ocelot is estimated to have diverged from the margay (Leopardus wieldii) between 2.41 and 1.01 mya. The relationships of the ocelot within the Felidae is considered as follows:[29][30]

Characteristics

The ocelot is not significantly sexually dimorphic, varying only slightly in mature maximum weight

The ocelot's fur is extensively marked with solid black markings on a creamy, tawny, yellowish, reddish gray or gray background color. The spots on the head and limbs are small, but markings on the back, cheeks, and flanks are open or closed bands and stripes. A few dark stripes run straight from the back of the neck up to the tip of the tail. Its neck and undersides are white, and the insides of the legs are marked with a few horizontal streaks. Its round ears are marked with a bright white spot.[6] Its fur is short, about 0.8 cm (0.3 in) long on the belly, but with about 1 cm (0.4 in) long guard hairs on the back.[2] The body has a notably strong odor.[31] Each ocelot has a unique color pattern, which can be used to identify individuals.[32] Its eyes are brown, but reflect in a golden hue when illuminated.[33] It has 28 to 30 teeth, with the dental formula 3.1.2–3.13.1.2.1.[2] It has a bite force quotient at the canine tip of 113.8.[34] Only one ocelot is known to possess albinism, and the appearance of such a trait in ocelots is likely an indication of deforestation.[35]

With a head-and-body length ranging from 55 to 100 cm (21.7 to 39.4 in) and a 30 to 45 cm (11.8 to 17.7 in) long tail, the ocelot is the largest member of the genus Leopardus.[6] It typically reaches 40–50 cm (15.7–19.7 in) at the shoulder.[2] The weight of females ranges between 7 and 12 kg (15 and 26 lb) and of males between 8 and 18 kg (17.6 and 39.7 lb).[6][36] Its footprint measures nearly 5 cm × 5 cm (2 in × 2 in).[37]

The ocelot can be confused with the margay (Leopardus wiedii) and the oncilla (L. tigrinus), though the ocelot is noticeably larger and heavier with a shorter tail. Though all three have rosettes on their coats, the ocelot typically has a more blotched pattern; the oncilla has dark spots on its underbelly unlike the other two. Other differences lie in the facial markings, appearance of the tail and fur characteristics.[6][38] The ocelot is similar in size to a bobcat (Lynx rufus), though larger individuals have occasionally been recorded.[39] The jaguar is notably larger and heavier, and has rosettes instead of spots and stripes.[40]

Distribution and habitat

Two ocelots, mother and daughter, in a wooded area of the Pantanal wetlands; at night, they encounter fewer humans on this farm.

The ocelot ranges from the southwestern United States to northern Argentina, up to an elevation of 3,000 m (9,800 ft).[1] In the United States, it is found in Texas and Arizona, and is extirpated from Louisiana and Arkansas.[41] Fossils of ocelots were found in Florida, specifically in the Reddick Fossil Site.[6][42]

It inhabits tropical forests, thorn forests, mangrove swamps and savannas.[6] A 2019 study in the Brazilian Amazon showed that it prefers habitats with good availability of prey and water, and tends to avoid other predators. It favors areas with dense forest cover and water sources, far from roads and human settlement, avoiding steep slopes and highly elevated areas due to lack of prey.[43][44][45] In areas where ocelots coexist with larger predators such as cougars and humans, they may tune their active hours to avoid them, and seek dense cover to avoid competitors.[46][47] It can adapt well to its surroundings; as such, factors other than the aforementioned are not significant in its choice of habitat.[45]

It shares a large part of its range with the jaguar, jaguarundi, margay, oncilla and cougar.[6]

Ecology and behavior

Ocelots rest in trees during the day

The ocelot is usually solitary and active mainly during twilight and at night. Radio collared individuals in the Cocha Cashu Biological Station in Peru rested during the day and became active earliest in the late afternoon; they moved between 3.2 and 17 hours until dawn and then returned to their dens.[48]

During the daytime, it rests on trees, in dens below large trees or other cool, sheltered sites on the ground. It is agile in climbing and leaping, and escapes predators by jumping on trees. It is also an efficient swimmer. It scent-marks its territory by spraying urine. The territories of males are 3.5–46 km2 (1.4–17.8 sq mi) large, while those of females cover 0.8–15 km2 (0.3–5.8 sq mi). Territories of females rarely overlap, whereas the territory of a male includes those of two to three females. Social interaction between sexes is minimal, though a few adults have been observed together even in non-mating periods, and some juveniles interact with their parents.[6] Data from camera trapping studies confirm that several ocelot individuals deposit scat in one or several communal sites, called latrines.[49][50][51] Ocelots can be aggressive in defending its territory, fighting even to death.[52]

The population density of ocelots has been observed to be high in areas with high rainfall, but tends to decrease with increasing latitude; highest densities have been recorded in the tropics.[53] In 2014, the ocelot population density in Barro Colorado Island was estimated to be 1.59–1.74/km2 (4.1–4.5/sq mi), greater than 0.984/km2 (2.55/sq mi) recorded in northwestern Amazon in Peru in 2010, which was the densest ocelot population recorded thus far.[54][55]

Potential predators of the ocelot in Texas include the cougar, coyote and American alligator, while ocelot kittens are vulnerable to raptors such as the great horned owl, as well as feral dogs, feral pigs and snakes.[56] Studies have found that adult ocelots are vulnerable to predation by both cougars and jaguars, with decreasing water sources in Guatemala causing predatory encounters with the latter.[57][58]

Hunting and diet

Ocelot hunting at night

Ocelots have been observed to follow scent trails to acquire prey. They walk slowly at a speed of about 0.3 km/h (0.2 mph) searching for prey.[48] Alternatively, an ocelot may wait for prey for 30 to 60 minutes at a certain site, and move to another walking at 0.8–1.4 km/h (0.5–0.9 mph) if unsuccessful. An ocelot typically prefers hunting in areas with vegetation cover, avoiding open areas, especially on moonlit nights, so as not to be seen by the prey. As a carnivore, it preys on small terrestrial mammals such as rodents, lagomorphs, armadillos, opossums, also fish, crustaceans, insects, reptiles and birds. It usually feeds on the kill immediately, but removes bird feathers before. It typically preys on animals that weigh less than 1 kg (2.2 lb), but rarely targets large ungulates such as deer, sheep and peccaries, as well as anteaters, monkeys and iguanas. It requires 600–800 g (21–28 oz) of food every day to satisfy its energy requirements.[6]

Primates prevail in the diet of ocelots in southeastern Brazil,[59] and iguanas in a tropical deciduous forest in Mexico.[60] The composition of the diet varies by season; in Venezuela, ocelots were found to prefer iguanas and rodents in the dry season and then switch to land crabs in the wet season.[61] In southeastern Brazil, ocelots have a similar prey preference as margays and oncillas. The oncillas focus on tree-living marsupials and birds while the margays are not as selective.[62]

Reproduction and life cycle

An ocelot kitten

Both male and female ocelots produce a long-range "yowl" in the mating season and a short-range "meow".[63] Ocelots can mate any time during the year. The peak mating season varies geographically; in Argentina and Paraguay peaks have been observed in autumn, and in Mexico and Texas in autumn and winter. Estrus lasts four to five days, and recurs every 25 days in a non-pregnant female.[36] A study in southern Brazil showed that sperm production in ocelots, margays and oncillas peaks in summer.[64] Captive ocelots spend more time together when mating; both scent-mark extensively and eat less during this time.[2] Breeding ocelots in captivity is often difficult.[65]

A litter of one to three is born after a gestation period of two to three months. Females give birth in dens, usually located in dense vegetation. A newborn kitten weighs 200–340 g (7.1–12.0 oz).[6][36] The kitten is born with spots and stripes, though on a gray background; the color changes to golden as the ocelot grows older.[31] A study in southern Texas revealed that a mother keeps a litter in a den for 13 to 64 days, and shifts the young to two or three dens.[66] The kitten's eyes open 15 to 18 days after birth. Kittens begin to leave the den at the age of three months. They remain with their mother for up to two years, and then start dispersing and establishing their own territory. In comparison to other felids, ocelots have a relatively longer duration between births and a narrow litter size. Captive ocelots live for up to 20 years.[6]

Threats

The ocelot is threatened by habitat loss and the fur and pet trades. It is still subject to poaching in spite of regional bans

Throughout its range, the ocelot is threatened by loss and fragmentation of habitat.[1] In Texas, the fertile land that supports dense cover and constitutes the optimum habitat for the ocelot is being lost to agriculture. The habitat is often fragmented into small pockets that cannot support ocelots well, leading to deaths due to starvation. Traffic accidents have emerged as a major threat over the years as ocelots try to expand beyond their natural habitat to new areas and get hit by vehicles.[67] In the Atlantic Forest in northeastern Argentina, it is affected by logging and poaching of prey species.[68]

The fur trade was a flourishing business in the 1960s and the 1970s that resulted in severe exploitation of felids such as the ocelot and the jaguar.[69] In the 1960s, ocelot skins were among the most highly preferred in the US, reaching an all-time high of 140,000 skins traded in 1970.[70] This was followed by prohibitions on commercial trade of spotted cat skins in several range states such as Brazil and the US, causing ocelot skins in trade to plummet.[69][71] In 1986, the European Economic Community banned import of ocelot skins, and in 1989, the ocelot was included in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. However, hunting of ocelots for skins has continued and is still a major threat to ocelot survival.[6]

Another threat has been the international pet trade; this typically involves capturing ocelot kittens by killing their mothers; these cats are then sold to tourists. Though it is banned in several countries, pet trade survives; in some areas of Central and South America ocelots are still sold in a few local markets.[72]

Conservation

The ocelot is listed as Least Concern on the IUCN Red List because of its wide distribution in the Americas. Ocelot hunting is banned in Argentina, Brazil, Bolivia, Colombia, Costa Rica, French Guiana, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Suriname, Trinidad and Tobago, the United States, Uruguay, and Venezuela; hunting is regulated in Peru. As of 2013, the global population was estimated at more than 40,000 mature individuals.[1] Ocelot populations were stable in some Amazon basin areas as of 2013.[73] As of 2012, the ocelot population in Argentina's subtropical regions was estimated to consist of 1,500 to 8,000 mature individuals.[74] It has been recorded in oil palm landscapes and big cattle ranches in the Colombian Llanos and inter-Andean valleys.[75]

In Texas

In Texas and northeastern Mexico, ocelot populations have reduced drastically; as of 2014, the population in Texas is estimated to be 50–80 individuals. The reduced numbers have led to increased inbreeding and low genetic diversity.[1][76] Despite this, the US Fish and Wildlife Service failed to acknowledge the ocelot population in Texas as a distinct population segment worthy of listing as endangered.[77] The US Fish and Wildlife Service, the Texas Parks and Wildlife Department and The Nature Conservancy are among agencies actively involved in ocelot conservation efforts, such as the protection and regeneration of vegetation in the Rio Grande Valley.[67][6] NatureServe considers the ocelot Apparently Secure globally, but Critically Imperiled in both Texas and Arizona.[78]

In captivity

The American Zoo and Aquarium Association established a Species Survival Plan for the ocelot populations in Brazil. In 2006, the captive population in North American zoos consisted of 16 ocelots representing six founders and their offspring. Some litters were produced using artificial insemination.[79] The Emperor Valley Zoo in Trinidad keeps foremost confiscated and trapped ocelots.[80]

In culture

Moche ceramic bottle in the shape of an ocelot, Musée d'ethnographie de Genève, Switzerland

Ocelots have been associated with humans since the time of the Aztec and Incan civilizations, who depicted ocelots in their art and mythology. Representations of ocelots appear in every artistic medium, from Moche ceramics to murals, architectural details, and landscape features. Ocelot bones were made into thin, pointed instruments to pierce ears and limbs for ritual bloodletting. Several figurines depicting ocelots and similar felids are known. In her 1904 work A Penitential Rite of the Ancient Mexicans, archaeologist Zelia Nuttall described a statue depicting an ocelot or another felid excavated in Mexico City and its relation to the Aztec deity Tezcatlipoca. She argued that the sculpture depicted an ocelot, writing,[81]

"According to the well-known myth, Tezcatlipoca, when cast down from heaven by Quetzalcoatl, "fell into the water where he transformed himself into an ocelot" and arose to kill certain giants.

Salvador Dalí with his pet ocelot Babou

Moreover, she described a photograph of a seated person to corroborate her claim:[81]

At the back of his head, above his left hand, the head of an ocelot is visible, whose skin hangs behind his back, the tail ending below his knee. Besides this the personage wears leggings made of the spotted ocelot skin and a rattlesnake girdle from which hang two conventionalized hearts. It is interesting to find that in a note written beneath its photograph the late Senor Islas de Bustamante, independently identified the above figure as a representation of "Ocelotl-Tezcatlipoca" or Tlatoca-ocelot, lit. the Lord Ocelot ... and described as wearing "the beard of the mask of Tezcatlipoca".

Like many other felids, occasionally ocelots are kept as pets. They might demand a lot of attention from their owners and have a tendency to chew on or suck on objects, such as fabric and the fingers of their owners; this can lead them to accidentally ingest objects such as tennis balls. Agile and playful, pet ocelots can be troublesome to keep due to their habit of leaping around and potentially damaging objects; ocelots may unintentionally injure their owners with bites. Nevertheless, carefully raised ocelots can be highly affectionate.[82] Painter Salvador Dalí kept a pet ocelot named Babou that was seen with him at many places he visited, including a voyage aboard SS France. When one of the diners at a New York restaurant was alarmed by his ocelot, Dali told her that it was a common domestic cat that he had "painted over in an op art design".[83][84][85][86] Opera singer Lily Pons and musician Gram Parsons are also known to have kept ocelots.[84][87]

Ocelot: Brief Summary

provided by wikipedia EN

The ocelot (Leopardus pardalis) is a medium-sized spotted wild cat that reaches 40–50 cm (15.7–19.7 in) at the shoulders and weighs between 7 and 15.5 kg (15.4 and 34.2 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 ocelot is efficient at climbing, leaping and swimming. It prefers areas close to water sources with dense vegetation cover and high prey availability. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. It is typically active during twilight and at night and tends to be solitary and territorial. Both sexes become sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically. After a gestation period of two to three months the female gives birth to a litter of one to three kittens. They stay with their mother for up to two years, after which they leave to establish their own home ranges.

The ocelot is listed as Least Concern on the IUCN Red List, and is threatened by habitat destruction, hunting, and traffic accidents. While its range is very large, various populations are decreasing in many parts of its range. The association of the ocelot with humans dates back to the Aztec and Incan civilizations; it has occasionally been kept as a pet.
