Listen to Mentally Stronger with therapist Amy Morin, wherever you get your podcasts. Welcome to the I Can't Sleep podcast, where I read random articles from across the web to bore you to sleep with my soothing voice. I'm your host, Benjamin Boster. Today's episode is from a Wikipedia article titled Cat. The Cat, Phyllis. is a domestic species of small coniferous mammal. It is the only domesticated species in the family
Starting point is 00:01:45 Felida and is often referred to as the domestic cat to distinguish it from the wild members of the family. A cat can either be a house cat, a farm cat, or a feral cat. The latter ranges freely and avoids human contact. Domestic cats are valued by humans, for companionship and their ability to hunt rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to other fielded species. It has a strong, flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Its night vision and sense of smell are well developed. Cat communication includes vocalization, like meowing, purring, trilling, hissing, growling, and grunting, as well as cat-specific body language.
Starting point is 00:02:50 A predator that is most active at dawn and dusk, crepuscular, a cat is a solitary hunter, but a social species. It can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small mammals. It secretes and perceives pheromones. Female domestic cats can have kittens from spring to late autumn, with litter sizes often ranging from two to five kittens. Domestic cats are bred and shown at events as registered pedigreed cats, a hobby known as cat fancy. Failure to control breeding of pet cats by spaying and neutering,
Starting point is 00:03:37 as well as abandonment of pets, resulted in large numbers of feral cats worldwide, contributing to the extinction of entire bird, mammal, and reptile species, and evoking population control. Cats were first domesticated in the Near East around 7,500 BC. It was long thought that cat domestication was initiated in ancient Egypt, as since around 3,100 BC veneration was. veneration was given to cats there. As of 2021, there are an estimated 220 million owned and 480 million stray cats in the world. As of 2017, the domestic cat was the second most popular
Starting point is 00:04:26 pet in the United States, with 95 million cats owned. In the United Kingdom, 26% of adults have a cat with an estimated population of 10.9 million pet cats as of 2020. Etymology and naming. The origin of the English word cat is thought to be the late Latin word catus, which was first used at the beginning of the 6th century. It was suggested that the word katus is derived from an Egyptian precursor of Coptic Sao Tomcat. or its feminine form suffixed with tea. The late Latin word may be derived from another Afro-Asiatic or Nilo-Saharan language.
Starting point is 00:05:22 The Nubian word Cadiska Wildcat and Nobin Cadiz are possible sources or cognates. The Nubian word may be a loan from Arabic, Kat, Keat. It is equally likely that the forms might derive from an ancient Germanic word, imported into Latin and thence to Greek and to Syriac and Arabic. The word may be derived from Germanic and Northern European languages and ultimately be borrowed from Urelic, female Stod, and Hungarian, Holgish Stod, from proto-Urelic, Cadvaa, female of a furred animal. A male cat is called a Tom or Tomcat or a Gib if neutered.
Starting point is 00:06:15 An unspayed female is called a queen, especially in a cat breeding context. A juvenile cat is referred to as a kitten. In early modern English, the word kitten was interchangeable with the now obsolete word catling. A group of cats can be referred to as a clouter or a glaring. taxonomy. The scientific name Phyllis Katus was proposed by Carl Linnaeus in 1758 for a domestic cat. Phyllis Katus Domesticus was proposed by Johann Christian Polycarp Ex Lerbin in 1777. Phelis Damon proposed by Constantine Alexevich Satinen in 1904 was a black cat from the Transcaucasus later identified as a domestic cat.
Starting point is 00:07:11 In 2003, the International Commission on Zoology Nomenclature ruled that the domestic cat is a distinct species, namely Ph.Catous. In 2007, it was considered a subspecies, F. Silvestris Katus, of the European Wildcat, F. Silvestris, following results of phylogenetic research. In 2017, the IUCN Cat Classification Task Force followed the recommendation of the ICZN in regarding the domestic cat as a distinct species, Phyllis Katus.
Starting point is 00:07:57 Evolution The domestic cat is a member of the Felida, a family that had a common ancestor about 10 to 15 million years ago. The genus Phyllis diverged from other Felida around the genus Félis diverged from other Felida around 6 to 7 million years ago. Results of phylogenetic research confirmed that the wild felus species evolved through sympatric or peripatric speciation, whereas the domestic cat evolved through artificial selection.
Starting point is 00:08:30 The domesticated cat and its closest wild ancestor are diploid and both possesses 38 chromosomes and roughly 20,000 genes. The leopard cat was tamed independently. in China around 5,500 BC. This line of partially domesticated cats leaves no trace in the domestic cat populations of today. Domestication The earliest known indication for the taming of an African wildcat was excavated close by a human Neolithic grave in Shilohracumbus, southern Cyprus, dating to about 7,500 to 7,200 B.C.
Starting point is 00:09:17 Since there is no evidence of native mammalian fauna on Cyprus, the inhabitants of this Neolithic village most likely brought the cat and other wild animals to the island from the Middle Eastern mainland. Scientists therefore assume that African wildcats were attracted to early human settlements in the fertile crescent by rodents, in particular the house mouse, and were tamed by a Neolithic farmers. This commensal relationship between early farmers and tamed cats lasted thousands of years.
Starting point is 00:09:56 As agricultural practices spread, so did tame and domesticated cats. Wildcats of Egypt contributed to the maternal gene pool of the domestic cat at a later time. The earliest known evidence for the occurrence of the domestic cat of the domestic cat, domestic cat in Greece dates to around 1,200 BC. Greek, Phoenician, Carthagian, and Etruscan traders introduced domestic cats to southern Europe. During the Roman Empire, they were introduced to Corsica and Sardinia before the beginning of the first millennium. By the 5th century BC, they were familiar animals around settlements in Magna Grisha and Etruria. By the end of the Roman Empire in the 5th century, the Egyptian domestic cat lineage had arrived in a Baltic seaport in northern Germany.
Starting point is 00:10:57 During domestication, cats have undergone only minor changes in anatomy and behavior, and they are still capable of surviving in the wild. Several natural behaviors and characteristics of wildcats may have pre-adapted them for domestication and animals. as pets. These traits include their small size, social nature, obvious body language, love of play, and relatively high intelligence. Captive leopardist cats may also display affectionate behavior toward humans, but were not domesticated. House cats often mate with feral cats, producing hybrids such as the Kellis cat in Scotland. Hybridization between domestic and other felonade species is also possible. Development of cat breeds started in the mid-19th century.
Starting point is 00:11:59 An analysis of the domestic cat genome revealed that the ancestral wildcat genome was significantly altered in the process of domestication as specific mutations were selected to develop cat breeds. Most breeds are founded on random, bred domestic cats. Genetic diversity of these breeds varies between regions and his lowest in purebred populations, which show more than 20 deleterious genetic disorders. Characteristics Size A domestic cat has a smaller skull and shorter bones than the European wildcat. It averages about
Starting point is 00:12:47 46 centimeters in head-to-body length and 23 to 25-cent. centimeters in height, with about a 30 centimeter long tail. Males are larger than females. Adult domestic cats typically weigh between 4 and 5 kilograms. Skeleton. Cats have 7 cervical vertebrae, as do most mammals. 13 thoracic vertebrae. Humans have 12.
Starting point is 00:13:20 7 lumbar vertebrae. Humans have 5. 3 sacral vertebrae. as do most mammals, but humans have five. And a variable number of caudal vertebrae in the tail. Humans have only vestigial caudal vertebrae fused into an internal coxix. The extra lumbar and thoracic vertebrae account for the cat's spinal mobility and flexibility. Attached to the spine are 13 ribs, the shoulder and the pelvis.
Starting point is 00:13:54 Unlike human arms, Cat four limbs are attached to the shoulder by free-floating clavicle bones, which allow them to pass their bodies through any space into which they can fit their head. Skull The cat's skull is unusual among mammals and having very large eye sockets and a powerful specialized jaw. Within the jaw cats have teeth adapted for killing prey and tearing meat. When it overpowers its prey, a cat deletioning. livers a lethal neck bite with its two long canine teeth, inserting them between two of the
Starting point is 00:14:33 prey's vertebrae and severing its spinal cord, causing irreversible paralysis and death. Compared to other felines, domestic cats have narrow-spaced canine teeth relative to the size of their jaw, which is an adaptation to their preferred prey of small rodents, which have small vertebrae. The pre-molar and first muller together composed the carnesial pair in each side of the mouth, which efficiently shears meat into small pieces, like a pair of scissors. These are vital in feeding, since cats' small molars cannot chew food effectively, and cats are largely incapable of mastication. Although cats tend to have better teeth than most humans, with decay generally less likely because of a thicker protective layer of enamel, a less damaging saliva, less retention of
Starting point is 00:15:34 food particles between teeth, and a diet mostly devoid of sugar, they are nonetheless subject to occasional tooth loss and infection. Claws. Cats have protractable and retractable claws. In their normal relaxed position, the claws are sheathed with the skin and fur around the paws' toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the four feet are typically sharper than those on the hind feet. Cats can voluntarily extend their claws on one or more paws. They may extend their claws in hunting or self-defense, climbing, kneading, or for extra traction on soft surfaces. Cats shed the outside layer of their claw sheaths when scratching rough surfaces.
Starting point is 00:16:37 Most cats have five claws on their front paws and four on their rear paws. A dew claw is proximal to the other claws. More proximally is a protrusion which appears to. to be a sixth finger. This special feature of the front paws on the inside of the wrists has no function in normal walking, but is thought to be an anti-skitting device used while jumping. Some cat breeds are prone to having extra digits. Polydactycptalus cats occur along North America's Northeast Coast and in Great Britain. Ambulation The cat is digited,
Starting point is 00:17:29 grade, it walks on the toes with the bones of the feet making up the lower part of the visible leg. Unlike most mammals, it uses a pacing gate and moves both legs on one side of the body before the legs on the other side. It registers directly by placing each hind paw close to the track of the corresponding forepaw, minimizing noise and visible tracks. This also provides sure footing for hind paws when navigating rough terrain. As it speeds up walking to trotting, its gate changes to a diagonal gate. A diagonally opposed hind and four legs move simultaneously.
Starting point is 00:18:14 Balance. Most breeds of cat have a noted fondness for sitting in high places or perching. A higher place may serve as a concealed sight from which to hunt. Domestic cats strike prey by pouncing from a purge, such as a tree branch. Another possible explanation is that height gives the cat a better observation point, allowing it to survey its territory. A cat falling from heights of up to three
Starting point is 00:18:47 meters can write itself and land on its paws. During a fall from a high place, a cat flexibly twists its body and writes itself to land on its feet using its acute sense of balance and flexibility. This reflex is known as the cat writing reflex. A cat always writes itself in the same way during a fall, if it has enough time to do so, which is the case in falls of 90 centimeters or more. How cats are able to write themselves when falling has been investigated as the falling cat problem. Senses. Vision Cats have excellent night. vision and can see at only one sixth the light level required for human vision. This is partly the
Starting point is 00:19:42 result of cat eyes having a tapetum lucidum which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light. Large pupils are an adaptation to dim light. The domestic cat has slit pupils which allow it to focus bright light without chromatic aberration. At low light, a cat's pupils expand to cover most of the exposed surface of its eyes. However, the domestic cat has rather poor color vision and only two types of cone cells, optimized for sensitivity to blue and yellowish green. Its ability to distinguish between red and green is limited. A response to middle wavelengths from a system other than the rod cells might be due to a third type of cone.
Starting point is 00:20:37 However, this appears to be an adaptation to low light levels rather than representing true trichromatic vision. Hearing The domestic cat's hearing is most acute in the range of 500 hertz to 32 kilohertz. It can detect an extremely broad range of frequencies ranging from 55 hertz to 79,000 hertz. It can hear a range of 10.5 octaves, while humans and dogs can hear ranges of about nine octaves.
Starting point is 00:21:16 Its hearing sensitivity is enhanced by its large movable outer ears, the Pinae, which amplify sounds and help detect the location of a noise. It can detect ultrasound, which enables it to detect ultrasonic calls made by rodent prey. Smell. Cats have an acute sense of smell. due in part to their well-developed olfactory bulb and a large surface of olfactory mucosa, about 5.8 square centimeters in area, which is about twice that of humans. Cats and many other animals have a Jacobson's organ in their mouths, and that is used in the behavioral process of Fleming.
Starting point is 00:22:06 It allows them to sense certain aromas in a way that humans cannot. cats are sensitive to pheromones such as three mycapto three methylbitin one hole which they use to communicate through urine spraying and marking with scent glands many cats also respond strongly to plants that contain nepotylactone especially catnip as they can detect that substance at less than one part per billion about 70 to 80 percent of cats are affected by nepotylactone. This response is also produced by other plants such as silver vine and the herb valerian. It may be caused by the smell of these plants mimicking a pheromone and stimulating cats social or sexual behaviors. Taste. Cats have relatively few taste buds compared to humans, 470 or so versus more than 9,000 on the human tongue. Domestic and wild cats are, Cats share a taste receptor gene mutation that keeps their sweet taste buds from binding to sugary molecules, leaving them with no ability to taste sweetness.
Starting point is 00:23:24 Their taste buds instead respond to acids, amino acids like protein, and bitter tastes. Cats also have a distinct temperature preference for their food, preferring food with a temperature around 38 degrees Celsius, which is similar to that of a fresh kill and routinely rejecting food presented cold. or refrigerated, which would signal to the cat that the prey item is long dead and therefore possibly toxic or decomposing. Whiskers. To aid with navigation and sensation, cats have dozens of movable whiskers over their body, especially their faces. These provide information on the widths of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents. They also trigger protective blink reflexes to protect the eyes from damage.
Starting point is 00:24:30 Behavior. Outdoor cats are active both day and night, although they tend to be slightly more active at night. Domestic cats spend the majority of their time in the vicinity of their homes, but can range many hundreds of meters from this central point. They establish territories that vary considerably in size, and one study ranging from seven. to 28 hectares. The timing of cats' activity is quite flexible and varied, which means house cats may be more active in the morning and evening as a response to greater human activity at these times. Cats conserve energy by sleeping more than most animals, especially as they grow older. The daily duration of sleep varies, usually between 12 and 16 hours, with 13 and 14 being the
Starting point is 00:25:28 average. Some cats can sleep as much as 20 hours. The term cat nap for a short rest refers to the cat's tendency to fall asleep lightly for a brief period. While asleep cats experience short periods of rapid eye movement sleep, often accompanied by muscle twitches which suggest they are dreaming. Sociability. The social behavior of the domestic cat ranges. from widely dispersed individuals to feral cat colonies that gather around a food source based on groups of cooperating females. Within such groups, one cat is usually dominant over the others. Each cat in a colony holds a distinct territory, with sexually active males having the largest territories, which are about ten times larger than those of female cats, and may overlap with several females territories.
Starting point is 00:26:33 These territories are marked by urine spraying by rubbing objects at head height with secretions from facial glands and by defecation. Between these territories are neutral areas where cats watch and creak one another without territorial conflicts. Outside these neutral areas, territory holders usually chase away stranger cats at first by staring, hissing, and growling. and if that does not work by short but noisy and violent attacks. Despite this colonial organization, cats do not have a social survival strategy or a pack mentality, and always hunt alone. Life in proximity to humans and other domestic animals has led to a symbiotic social adaptation in cats, and cats may express great affection toward humans or other animals.
Starting point is 00:27:31 Aeologically, the human keeper of a cat functions as a sort of surrogate for the cat's mother. Adult cats live their lives in a kind of extended kittenhood, a form of behavioral neotony. Their high-pitched sounds may mimic the cries of a hungry human infant, making them particularly difficult for humans to ignore. However, some pet cats are poorly socialized. In particular, older cats show aggressiveness. show aggressiveness towards newly arrived kittens, which include biting and scratching. This type of behavior is known as feline as social aggression. Domestic cats scent-rubbing behavior towards humans or other cats is thought to be a feline
Starting point is 00:28:17 means for social bonding. Communication Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling, snarling, grunting, and several different forms of meowing. Their body language, including position of ears and tail, relaxation of the whole body, and kneading of the paws are all indicators of mood. The tail and ears are particularly important social signal mechanisms in cats. A raised tail indicates a friendly greeting and flattened ears indicates hostility.
Starting point is 00:29:04 Tail raising also indicates the cat's position in the group's social hierarchy, with dominant individuals raising their tails less often than subordinate ones. Feral cats are generally silent. Nose-to-nose touching is also a common greeting, and may be followed by social grooming, which is solicited by one of the cats raising and tilting its head. Purring may have developed as an evolutionary advantage, has a signaling mechanism of reassurance between mother cats and nursing kittens.
Starting point is 00:29:41 Post-nursing cats often purr as a sign of contentment, when being pitted, becoming relaxed, or eating. The mechanism by which cats purr is elusive. A cat has no unique anatomical feature that is clearly responsible for the sound. Grooming. Cats are known for spending considerable amounts of time licking their coats to keep them clean. The cat's tongue has backwards-facing spines about 500 micrometers long, which are called papillet. These contain carrot and which makes them rigid, so the papillet act like a hairbrush. Some cats, particularly long-haired cats, occasionally regurgitate hairballs of fur that have collected in their stomachs from grooming.
Starting point is 00:30:35 His clumps of fur usually sausage-shaped in about two to three centimeters long. Hair balls can be prevented with remedies that ease elimination of the hairs through the gut, as well as regular grooming of the coat with a comb or sift brush. Fighting Among domestic cats, males are more likely to fight than females. Among feral cats, the most common reason for cat fighting is competition between two males to mate with female. In such cases, most fights are won by the heavier male. Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home.
Starting point is 00:31:22 Female cats also fight over territory or to defend their kittens. Nuterine will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones. When cats become aggressive, they try to make themselves appear larger and more threatening by raising their fur, arching their backs, turning sideways, and hissing or spitting. Often the ears are pointed down and back to avoid damage to the inner ear, and potentially listen for any changes behind them while focused forward. It may also vocalize loudly and bear their teeth in an effort to further intimidate their opponent. Fights usually consist of grappling and delivering powerful slaps to the face and body with the forepaws,
Starting point is 00:32:12 as well as bites. Cats also throw themselves to the ground in a defensive posture to rake their opponent's belly with their powerful hind legs. Serious damage is rare, as the fights are usually short in duration, with the loser running away with little more than a few scratches to the face and ears. However, fights for mating rights are typically more severe, and injuries may include deep puncture wounds and last. Saurations. Normally, serious injuries from fighting are limited to infections of scratches and bites,
Starting point is 00:32:51 though these can occasionally kill cats if untreated. In addition, bites are probably the main route transmission of feline immunodeficiency virus. Sexually active males are usually involved in many fights during their lives and often have decidedly battered faces with obvious scars and cuts to their ears and nose. Hunting and feeding. The shape and structure of cat's cheeks is insufficient to allow them to take in liquids using suction. Therefore, when drinking, they lap with the tongue to draw liquid upwards into their mouths. Lapping at a rate of four times a second, a cat touches the smooth tip of its tongue to the surface of the water, and quickly retracts it like a corkscrew drawing water upwards.
Starting point is 00:33:52 Feral cats and free-fed house cats consume several small meals in a day. The frequency and size of meals varies between individuals. They select food based on its temperature, smell, and texture. They dislike chilled foods and respond most strongly to moist foods rich in amino acids. which are similar to mead. Cats reject novel flavors, a response termed neophobia, and learn quickly to avoid foods that have tasted unpleasant in the past. It is also a common misconception that cats like milk or cream
Starting point is 00:34:30 as they tend to avoid sweet food and milk. Most adult cats are lactose intolerant. The sugar and milk is not easily digested that may cause soft stools or diarrhea. Some also develop odd eating habits and like to eat or chew on things like wool, plastic, cables, paper, string, aluminum foil, or even coal. This condition, PICA, can threaten their health
Starting point is 00:35:00 depending on the amount and toxicity of the items eaten. Cats hunt small prey, primarily birds and rodents, and are often used as a form of pest. control. Cats use two hunting strategies, either stalking prey actively or waiting in ambush until an animal comes close enough to be captured. Cats use two hunting strategies, either stalking prey actively or waiting in ambush until an animal comes close enough to be captured. The strategy used depends on the prey species in the area, with cats waiting in ambush outside burrows, but tending to actively stock birds.
Starting point is 00:35:49 Domestic cats are a major predator of wildlife in the United States, killing an estimated 1.3 to 4 billion birds and 6.3 to 22.3 billion mammals annually. Certain species appear more susceptible than others. For example, 30% of house sparrow mortality is linked to the domestic cat. In the recovery of Ringed Robbins and Dunnaks, 31% of deaths were a result of cat predation. In parts of North America, the presence of larger carnivores such as coyotes, which prey on cats and other small predators, reduces the effect of predation by cats and other small predators, such as opossums and raccoons, on bird numbers and variety.
Starting point is 00:36:41 perhaps the best known element of cats hunting behavior, which is commonly misunderstood and often appalled cat owners because it looks like torture, is that cats often appear to play with prey by releasing it after capture. This cat and mouse behavior is due to an instinctive imperative to ensure that the prey is weak enough to be killed without endangering the cat. Another poorly understood element of cat hunting behavior is the presentation of prey to human guardians. One explanation is that cats adopt humans into their social group and share excess skill with others in the group, according to the dominance hierarchy, in which humans are reacted to as if they are at or near the top. Another explanation is that they attempt to teach their guardians to hunt or to help their human as if feeding an elderly cat or an inept kitten. This hypothesis is inconsistent with the fact that male cats also bring home prey, despite males having negligible involvement in raising kittens.
Starting point is 00:38:01 Play Domestic cats, especially young kittens, are known for their love of play. this behavior mimics hunting and is important in helping kittens learn to stalk, capture, and kill prey. Cats also engage in play fighting with each other and with humans. This behavior may be a way for cats to practice the skills needed for real combat and might also reduce any fear they associate with launching attacks on other animals. Cats also tend to play with toys more when they are hungry. Owing to the close similarity between play and hunting,
Starting point is 00:38:48 cats prefer to play with objects that resemble prey, such as small furry toys that move rapidly but rapidly lose interest. They become habituated to a toy they have played with before. String is often used as a toy, but if it is eaten, it can become caught at the base of the cat's tongue and then move into the intestines, a medical emergency which can cause serious illness, even death. Owing to the risks posed by cats eating string, it is sometimes replaced with a laser pointer's dot, which cats may chase. Lifespan and health
Starting point is 00:39:37 The average lifespan of pet cats has risen in recent decades. In the early 1980s, it was about seven years rising to 9.4 years in 1995 and 15.1 years in 2018. Some cats have been reported as surviving into their 30s, with the oldest known cat, cream puff, dying at a verified age of 38. neutering increases life expectancy. One study found castrated male cats live twice as long as intact males, while spayed female cats live 62% longer than intact females. Having a cat neutered confers health benefits, because castrated males cannot develop testicular cancer,
Starting point is 00:40:29 spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. Disease. About 250 heritable genetic disorders have been identified in cats, many similar to human inborn errors or metabolism. The high level of similarity among the metabolism of mammals allows many of these feline diseases to be diagnosed using genetic tests that were originally developed for use in humans,
Starting point is 00:41:08 as well as the use of cats as animal models in the study of the human diseases. Diseases affecting domestic cats include acute infections, parasitic infections, injuries, and chronic diseases such as kidney disease, thyroid disease, and arthritis. Vaccinations are available for many infectious diseases, as are treatments to eliminate parasites, such as are treatments, to eliminate parasites, such as is worms, ticks, fleas, ecology. Habitats. The domestic cat is a cosmopolitan species and occurs across much of the world. It is adaptable and now present on all continents except Antarctica,
Starting point is 00:41:59 and on 118 of the 131 main groups of islands, even on the isolated Kerguelen islands. Due to its ability to thrive in almost any terrestrial habitat, it is among the world's most invasive species. As it is little altered from the wildcat, it can readily interbreed with the wildcat. This hybridization poses a danger to the genetic distinctiveness of some wildcat populations, particularly in Scotland and Hungary, and possibly also the Iberian Peninsula. It lives in small islands with no human inhabitants.
Starting point is 00:42:40 Farrell cats can live in. in forests, grasslands, dundra, coastal areas, agricultural land, scrublands, urban areas, and wetlands. Feral cats. Feral cats are domestic cats that were born in or have reverted to a wild state. They are unfamiliar with and wary of humans and roam freely in urban and rural areas. The numbers of feral cats is not known, but estimates of the animals of feral cats is not known, but estimates of the United States feral population range from 25 to 60 million. Feral cats may live alone, but most are found in large colonies, which occupy a specific territory, and are usually associated with a source of food. Famous feral cat colonies are found in Rome around the Coliseum and Forum
Starting point is 00:43:43 Romainum, with cats at some of these sites being fed and given medical attention by volunteers. Public attitudes towards feral cats vary widely from seeing them as free-ranging pets to regarding them as vermin. One common approach to reducing the feral cat population is termed trap-neuter return, where the cats are trapped, neutered, immunized against diseases, such as rabies and the feline panlochopinia and leukemia viruses, and the cats. and then released.
Starting point is 00:44:20 Before releasing them back into their feral colonies, the attending veterinarian often nips the tip off one ear to mark it is neutered and inoculated, since these cats may be trapped again. Volunteers continue to feed and give care to these cats throughout their lives. Given this support, their lifespans are increased and behavior and nuisance problems caused by competition for food or Some feral cats can be successfully socialized and retamed for adoption.
Starting point is 00:44:56 Young cats, especially kittens, and cats that have had prior experience and contact with humans are the most receptive to these efforts. Impact on wildlife. On islands, birds can contribute to as much as 60% of a cat's diet. In nearly all cases, however, the cat cannot be able to. be identified as the sole cause for reducing the numbers of island birds.
