a6:Tae2af,Everything About Cats — and Everything That Isn’t

An unfinishable book

Everything About Catsand Everything That Isn't

Scroll to read. It does not end.

This is an attempt to write down everything there is to know about cats, and, because the first task is impossible, also everything there isn't. It does not succeed. It is not designed to succeed. It is designed to go on longer than you will.

There is no navigation, no search, no index, no sidebar, no account, no settings, and nothing to click. There is one thing a reader can do here, and that is read. When you reach the bottom of what is written, more is written. This continues for as long as you continue, and then a little longer.

The entries below are numbered because they have to be numbered in order to be counted, but the numbers do not mean progress. Entry four hundred thousand is not nearer the end than entry four. There is no end. A cat would understand this arrangement immediately and would not be impressed by it.

What follows is drawn from anatomy, genetics, veterinary medicine, archaeology, etymology, folklore, the history of ships and grain stores, the behaviour of colonies in car parks, and the enormous body of things people are confident about regarding cats that turn out, on inspection, to be unresolved. The second category is not smaller than the first. It may be larger. This is the honest situation with cats, and it is why the subject is inexhaustible rather than merely long.

Begin anywhere. Stop anywhere. Nothing is lost by stopping, because nothing was ever going to be completed.

1What Is Not Known of Tabby Stripes

It has been noted, repeatedly and in many languages, that tabby Stripes, and everything attached to it. Cats have five toes on each front paw and usually four on each hind paw, and the fifth front toe is a raised dewclaw that acts like a thumb when gripping. In principle, a cat's hunting success rate is generally under a third of attempts, which is respectable for a solitary hunter. Nobody knows why cats occasionally react with alarm to a person they have known for years wearing something new. A cat that has never been outdoors will investigate a new object nose-first and then pretend it never existed, and every part of it is inherited from an animal that hunted alone in dry country. A cat exposing its belly is showing trust but is not usually asking for a belly rub, and many cats will make this clear, although a cat asked to demonstrate this will decline.

Nobody knows whether the therapeutic effect of living with a cat is the cat, the routine, or the touch. Even so, nobody knows how much of a cat's personality is genetic and how much is the first nine weeks of its life. Nobody knows what proportion of a cat's vocalisations are directed at us and what proportion are simply overheard, and every cat you meet will complicate it. Set beside that, one thing is solid: those papillae make a cat's tongue an extraordinarily efficient comb, but they also mean anything a cat gets on its tongue tends to travel in only one direction: down.

A patient reader will eventually arrive at tabby Stripes. Cats spread along trade routes and shipping lanes, kept aboard because ships carried grain and grain carried rats. Behaviourally, a cat that stops grooming, or grooms one spot obsessively, is usually telling you where the pain is. The socialisation window for kittens runs from roughly two to seven or nine weeks, and gentle handling in that period does more for a cat's lifelong friendliness than anything afterwards, though the cat itself offers no comment. Cats can be taught to sit, to come, to give a paw, to enter a carrier voluntarily, and to tolerate nail trims.

The American Shorthair has a temperament reputation that individual cats routinely ignore. The Oriental Longhair was assembled from a small founding population, with everything that implies, and the Pixie-bob shows how quickly a population can be reshaped once humans start choosing. Seen from the cat's side, a cat's hunting success rate is generally under a third of attempts, which is respectable for a solitary hunter. It is not known whether cats dream in images, in smells, in sounds, or in something for which we have no word, which is easy to verify and easy to forget.

A colony cat in a car park will sit for twenty minutes without moving anything but the tips of its ears, and the human reading of it is usually generous and usually wrong. A ship's cat will announce itself at a closed door and then decline to go through it. Seen from the cat's side, a layer of reflective tissue behind the retina, the tapetum lucidum, bounces light back through the photoreceptors a second time and gives a cat roughly six times better vision in low light than a human. It is unknown whether the cat's apparent indifference is genuine or a form of composure, which accounts for a surprising amount of what follows.

It is unknown how many distinct meow sounds a single cat is capable of producing. Anecdotally, it is unknown how many distinct meow sounds a single cat is capable of producing. Nobody knows why the domestic cat's coat pattern varies so wildly when its wild ancestor's does not, which accounts for a surprising amount of what follows. Set beside that, one thing is solid: kittens are born blind and deaf, with sealed eyes and folded ear canals, and are entirely dependent on warmth and smell.

Veterinary practice has a great deal to say about tabby Stripes. The active compound in catnip is nepetalactone, which appears to bind to receptors in the nasal tissue rather than being tasted. And yet, the oldest surviving poem about a specific pet cat in English is arguably about Jeoffry, in Christopher Smart's Jubilate Agno, written in an asylum in the eighteenth century. Veterinarians have documented a phenomenon called high-rise syndrome, in which cats falling from greater heights sometimes sustain fewer injuries than those falling from lower ones, because there is time to right, relax, and spread out, and this is one of the few points on which nearly everyone agrees. Those papillae make a cat's tongue an extraordinarily efficient comb, but they also mean anything a cat gets on its tongue tends to travel in only one direction: down.

The list continues below, as it will continue below whatever is below.

2Further Observations on Old Age

Nothing prepares the reader for old Age. Trap-neuter-return is the best-evidenced method of stabilising and slowly shrinking feral colonies. Statistically, muhammad is traditionally described as fond of cats, and there is a long tradition of cats being welcome in mosques. Toxoplasma gondii completes its sexual life cycle only in cats, which is the entire reason the parasite is a matter of public health interest, though the cat itself offers no comment. The Norwegian Forest Cat, the Siberian, and the Maine Coon all independently developed a dense double coat, a ruff, and tufted ears in cold climates.

The Ocicat has a temperament reputation that individual cats routinely ignore. The Lykoi exists because one cat somewhere was unusual and somebody kept the kittens, and the Savannah shows how quickly a population can be reshaped once humans start choosing. To put the same point differently, killing a cat in ancient Egypt could be a capital offence, and the export of cats was at times restricted. It is not known whether cats understand that the animal in a video on a screen is not present, although a cat asked to demonstrate this will decline.

Veterinary practice has a great deal to say about old Age. Cats have scent glands between the toes, so scratching leaves both a visual mark and a chemical one. Statistically, before clay litter, indoor cats used sand, ash, or dirt, and most cats therefore lived at least partly outdoors. Cats can rotate their forelimbs far more freely than dogs, which is what allows the precise, hand-like use of a paw to fish something out of a narrow gap, though it is not the whole story and probably never will be. Cats naturally eat a dozen or more small meals in a day, which fits a hunting pattern of many small kills rather than one large one.

The Aegean is admired for a coat that is really a single mutation held in place by human preference. The Sokoke is a breed whose written standard is younger than most of the people reading about it, and the Savannah shows how quickly a population can be reshaped once humans start choosing. To put the same point differently, a cat named Félicette was launched into space by France in 1963 and is the only cat known to have flown, and survived, a suborbital flight. It is unknown why cats will use a cardboard box for weeks and then never again, though the exceptions are numerous and unrepentant.

The carnassial teeth is under far more voluntary control than most owners realise. Cats have their own genome project, and the reference genome is built largely from an Abyssinian named Cinnamon. Just as reliably, the pupils is under far more voluntary control than most owners realise. Nobody knows whether the cat that sits on a laptop wants warmth, wants attention, or has simply decided that this is where a cat goes.

Somewhere a cat is doing something not yet described here.

3What Is Not Known of Ships

Observers have long remarked upon ships. The nine lives of a cat are seven in much of Spanish and Turkish tradition and six in some Arabic tradition. For all that, cats can hear frequencies up to roughly sixty-four kilohertz, nearly two octaves above the human ceiling, which lets them hear the ultrasonic squeaks of mice. Toxoplasma gondii completes its sexual life cycle only in cats, which is the entire reason the parasite is a matter of public health interest, and the mechanism is better described than explained. A layer of reflective tissue behind the retina, the tapetum lucidum, bounces light back through the photoreceptors a second time and gives a cat roughly six times better vision in low light than a human.

Nobody knows whether the therapeutic effect of living with a cat is the cat, the routine, or the touch. By contrast, nobody knows why some cats respond to catnip and others do not, beyond the fact that the difference is inherited. Nobody knows what cats make of their own reflections in water, or of the cat on the other side of a window, and the honest position is uncertainty. Set beside that, one thing is solid: cats prefer human interaction to food in some experimental settings, which surprised a great many people.

The European Shorthair was named for a place it did not come from. The Singapura is banned, restricted, or unrecognised by at least one major registry, and the Suphalak is a long coat draped over an ordinary cat, which is true of more breeds than the fancy admits. For all that, petting-induced aggression, in which a purring cat suddenly bites, is generally the cat having reached the end of a tolerance that was never unlimited. It is unknown whether such homing stories are a real ability or a very small number of lucky cats reported out of a great many lost ones, and it has been rediscovered by every generation of cat owners independently.

The Norwegian Forest Cat has a temperament reputation that individual cats routinely ignore. The Japanese Bobtail shows how quickly a population can be reshaped once humans start choosing, and the Arabian Mau was named for a place it did not come from. Less romantically, a cat that is genuinely relaxed will often blink first and then look away; staring without blinking is, in cat manners, a threat. It is unknown why feline hyperthyroidism went from rare to common within a single human generation, and the honest position is uncertainty.

A shorthaired cat in winter will sleep through a party and wake at the sound of a tin opening, so the apparent indifference is really attention pointed elsewhere. A cat that has decided in your favour will fall asleep mid-groom with one leg still raised. And yet, the scientific name for a whisker is a vibrissa, and a cat carries them not only on the muzzle but above the eyes, on the cheeks, on the chin, and on the back of the front legs. Nobody knows why the domestic cat's coat pattern varies so wildly when its wild ancestor's does not, and this is one of the few points on which nearly everyone agrees.

Consider, for a moment, ships. Cats have five toes on each front paw and usually four on each hind paw, and the fifth front toe is a raised dewclaw that acts like a thumb when gripping. Less romantically, cats can hear frequencies up to roughly sixty-four kilohertz, nearly two octaves above the human ceiling, which lets them hear the ultrasonic squeaks of mice. Cats appear to understand object permanence at least partially, tracking where something went after it disappeared, and this is one of the few points on which nearly everyone agrees. The Bengal descends from crosses with the Asian leopard cat, and early generations retain a good deal of wild temperament.

Consider, for a moment, ships, and everything attached to it. Microchipping is the single most reliable way a lost cat gets home, and it works only if the registration details are current. Historically, kittens are born blind and deaf, with sealed eyes and folded ear canals, and are entirely dependent on warmth and smell. Nobody knows how many cats there are on earth, and estimates for free-ranging cats vary by hundreds of millions. A colony cat in a car park will investigate a new object nose-first and then pretend it never existed, and none of it requires our approval. The Egyptian Mau is one of the few naturally spotted domestic breeds, which is true of some cats and untrue of the cat sleeping nearest to you.

A ship's cat will attend to a sound no human in the room can hear, and it will do the same thing tomorrow at the same hour. A barn cat with a job to do will lose interest at precisely the moment of success. Against that, a male cat is a tom, an unspayed female is a queen, and a neutered male was once called a gib. Nobody knows whether the cat that sits on a laptop wants warmth, wants attention, or has simply decided that this is where a cat goes, though the evidence is thinner than the confidence with which it is usually stated.

That is one page of it. There are more pages than there are cats, and there are a great many cats.

4What Is Not Known of Being Ignored

There remains the matter of being Ignored, and everything attached to it. Cats evolved in arid country and have a weak thirst drive, taking most of their historical water intake from the bodies of their prey. Loosely speaking, cats evolved in arid country and have a weak thirst drive, taking most of their historical water intake from the bodies of their prey. Nobody knows why a cat's tolerance for petting ends when it ends. A cat at the top of a bookcase will choose the least comfortable chair in the room, and the whole sequence takes less than a second when it finally happens. Almost all orange cats are male, because the gene for orange fur sits on the X chromosome and a male needs only one copy, which is why the subject refuses to close.

The Norwegian Forest Cat exists because one cat somewhere was unusual and somebody kept the kittens. The Ragamuffin is banned, restricted, or unrecognised by at least one major registry, and the Suphalak is a breed whose written standard is younger than most of the people reading about it. Historically, female cats are induced ovulators and can come into heat again within weeks of giving birth, which is how an unspayed pair becomes a colony with such speed. It is unknown why a cat's chirping trill exists at all, since it seems to be used for greeting, for kittens, and for windows, which no amount of observation seems to exhaust.

Nothing prepares the reader for being Ignored. Almost all orange cats are male, because the gene for orange fur sits on the X chromosome and a male needs only one copy. Just as reliably, the Singapura is among the smallest recognised breeds, with adults sometimes under three kilograms. The chattering bite a cat makes in the air while watching a bird out of reach is called vacuum activity, a hunting behaviour with nowhere to go, which accounts for a surprising amount of what follows. Purring occurs at frequencies between roughly twenty and one hundred and fifty hertz and is produced by rapid twitching of the laryngeal muscles that interrupts the flow of air in both directions.

One might reasonably start with being Ignored, and everything attached to it. The Chartreux, the Russian Blue, the Korat, and the British Blue are four separate breeds that arrived independently at a similar blue-grey coat. Less romantically, the response to catnip is inherited, and somewhere between a third and a half of cats are simply indifferent to it. Nobody knows what cats make of their own reflections in water, or of the cat on the other side of a window. A longhaired cat in summer will refuse the expensive bed in favour of the box it came in, and it will do the same thing tomorrow at the same hour. The patches on a calico are a visible map of which X chromosome switched off in which patch of embryonic skin, making every calico a unique photograph of its own development, though it is not the whole story and probably never will be.

Observers have long remarked upon being Ignored. Muhammad is traditionally described as fond of cats, and there is a long tradition of cats being welcome in mosques. Less romantically, the Cheshire Cat's grin outlasting the cat itself is one of the most quoted images in English nonsense literature. An odd-eyed white cat is sometimes deaf only on the blue-eyed side, and the mechanism is better described than explained. The oldest cat whose age is reasonably documented, Creme Puff of Austin, Texas, is reported to have lived to thirty-eight.

A feral tom with a torn ear will investigate a new object nose-first and then pretend it never existed, and none of it requires our approval. A kitten of nine weeks will choose the least comfortable chair in the room. More usefully, the Savannah descends from crosses with the African serval and can be extremely large, which is why several jurisdictions regulate the early generations. Nobody knows exactly why cats purr, in the sense that no single explanation accounts for every occasion on which they do it, which accounts for a surprising amount of what follows.

The list continues below, as it will continue below whatever is below.

5An Aside on Obligate Carnivory

The Devon Rex shows how quickly a population can be reshaped once humans start choosing. The Manx is a long coat draped over an ordinary cat, which is true of more breeds than the fancy admits, and the Devon Rex carries a conformation that veterinarians have opinions about. Strictly speaking, cats can be trained with a clicker as reliably as dogs, and the reason so few people do it is cultural rather than feline. It is unknown whether a cat can feel something like affection in the way a human means the word, or something adjacent that we lack a name for, which is more interesting than it first appears.

The Cornish Rex was named for a place it did not come from. The Toyger is banned, restricted, or unrecognised by at least one major registry, and the Dragon Li shows how quickly a population can be reshaped once humans start choosing. Behaviourally, even a solid black cat is genetically a tabby underneath, and in strong sunlight you can often see the ghost of its stripes. Nobody knows whether cats hear human music as music, though there is evidence they respond to music composed in feline vocal ranges, which is easy to verify and easy to forget.

The whiskers is more nerve than the eye suggests. Cats appear in the earliest literature: in Aesop, in the Sanskrit Panchatantra, in Japanese court diaries. Less romantically, the ears is more nerve than the eye suggests. Nobody knows exactly why cats knead, and every explanation offered is plausible without being demonstrated.

It cannot be avoided: obligate Carnivory, and everything attached to it. The domestic cat, Felis catus, is a small obligate carnivore that has lived alongside human beings for roughly ten thousand years. Anatomically, a cat's preference for sitting on paper, laptops, and open books is a preference for warmth, for scent, and for the attention of whoever is using them. Nobody knows what proportion of a cat's vocalisations are directed at us and what proportion are simply overheard. A cat at the top of a bookcase will knock exactly one thing off a surface and walk away satisfied, which is why cats seem simultaneously predictable and impossible to predict. The cat flap is often attributed to Isaac Newton, though the story is almost certainly a later invention, which is why the subject refuses to close.

Veterinary practice has a great deal to say about obligate Carnivory, and everything attached to it. The Japanese Bobtail is the cat of the beckoning maneki-neko figurine, and its short kinked tail comes from a mutation unrelated to the Manx. Rather more to the point, the Ragdoll is named for a tendency to go limp when picked up. Nobody knows why cats sometimes stop eating a food they have eaten happily for years. A barn cat with a job to do will fall asleep mid-groom with one leg still raised, which is how a solitary hunter budgets its energy. A cat drinks by curling the tip of its tongue backward, touching the surface, and whipping it up fast enough to draw a column of water into the mouth, and this is one of the few points on which nearly everyone agrees.

It is unknown whether cats experience anything like boredom in the reflective human sense, or only unspent energy. For all that, it is not known why cats bite gently, and whether the gradation between a love bite and a warning is deliberate. Nobody knows how many of the behaviours we call training are the cat training us, although a cat asked to demonstrate this will decline. Set beside that, one thing is solid: a cat urinating outside the tray is far more often reporting a medical problem or a stressor than expressing spite.

An orange tom of great confidence will fall asleep mid-groom with one leg still raised, and the human reading of it is usually generous and usually wrong. A barn cat with a job to do will make itself longer than seems anatomically permitted. Statistically, a cat's preference for sitting on paper, laptops, and open books is a preference for warmth, for scent, and for the attention of whoever is using them. It is not known whether a cat experiences its purr as a deliberate act or as something closer to breathing, and this is one of the few points on which nearly everyone agrees.

Consider, for a moment, obligate Carnivory. A cat that stops grooming, or grooms one spot obsessively, is usually telling you where the pain is. Historically, the response to catnip is inherited, and somewhere between a third and a half of cats are simply indifferent to it. Cats are digitigrade: they walk on their toes, with the visible backward-bending joint on the hind leg being an ankle rather than a knee, and it has been rediscovered by every generation of cat owners independently. Cats can taste bitterness with unusual acuity, which is thought to be a defence against the alkaloids in spoiled meat and toxic plants.

The list continues below, as it will continue below whatever is below.

6Measurements of Nine Lives

Little is settled concerning nine Lives, and everything attached to it. Male cats in colonies tend to have larger, overlapping ranges than females, and much of the fighting is about those overlaps. More usefully, a cat's normal body temperature runs between about thirty-eight and thirty-nine degrees Celsius, warmer than a human's, which is part of why cats seek out warm places that would be uncomfortable for us. Nobody knows how many cats there are on earth, and estimates for free-ranging cats vary by hundreds of millions. A small grey cat with no name will choose the least comfortable chair in the room, which tells you what the cat is measuring. A group of cats is a clowder, and a group of kittens is a kindle, though the exceptions are numerous and unrepentant.

The floating clavicle changes function entirely depending on what the rest of the animal is doing. Cats stare at nothing because they have heard something in the wall that you have not. More usefully, the laryngeal muscles is the reason a cat can do something a dog of the same weight cannot. Nobody has established what a cat believes a human to be: an enormous incompetent cat, a different kind of animal entirely, or something without a category.

Across ten thousand years, nine Lives. The Chartreux, the Russian Blue, the Korat, and the British Blue are four separate breeds that arrived independently at a similar blue-grey coat. Strictly speaking, the word puss is very old and appears across Germanic languages, but its origin is unclear. Every tabby carries a faint M on the forehead, and there is folklore in several cultures explaining it, which is true of some cats and untrue of the cat sleeping nearest to you. Cats purr at frequencies that overlap with those used therapeutically to promote bone density, which has led to a good deal of speculation and some genuine research.

Nobody knows how many of the behaviours we call training are the cat training us. To put the same point differently, it is unknown whether a cat perceives the passage of an afternoon as long or short. It is unknown whether a cat's slow blink is voluntary in the way a human wink is, and every cat you meet will complicate it. Set beside that, one thing is solid: cats reached Cyprus by boat, because there were never wildcats on the island.

It is unknown whether a cat conceives of its territory as a map, a set of routes, or a sequence of smells. Anatomically, nobody knows whether the cat that sits on a laptop wants warmth, wants attention, or has simply decided that this is where a cat goes. Nobody knows why a cat's tolerance for petting ends when it ends, and the literature has been arguing about it since the nineteen-sixties. Set beside that, one thing is solid: a cat with a puffed tail and an arched back is trying to look larger, which is a defensive display rather than an attack.

b0:[] b1:T4a9,I'm structuring this as a cat content generator with a vocabulary corpus and a deterministic text generator that produces infinite paragraphs from a seeded index, then building an API endpoint to serve paginated chunks and a reading interface with infinite scroll on the client side. Now I'm designing the styling—serif font, cream background, generous line height to keep it readable and minimal. For the corpus itself, I'm creating a rich bank of content using templates with word slots that create combinatorial variety: fact statements, speculation about unknowns, breed information, body parts, behaviors, sounds, postures, places, and times. I'll seed a PRNG from the chunk index so the same page always generates the same text, and organize each chunk as numbered entries with headings followed by multiple paragraph types—facts, unknowns, taxonomies, anecdotes, etymologies, and breed catalogs. With a few hundred entries in each word bank, the combinatorics will generate effectively infinite unique content. I'm also adding a word counter display showing "you have read X of ∞" to give a sense of scale. Now I'll write the TypeScript module that builds this corpus generator.b2:T413,I'm sketching out a new API endpoint that streams encyclopedia entries to the client. The server will accept a starting entry number and optionally some recent topics to avoid duplication, then select topics from a predefined list (seeded by the entry number for variety) and prompt the model to generate multiple entries with formatted headings and delimiters so the client can parse them incrementally as the stream arrives. On the client side, I'll read the stream progressively, split entries by the delimiter, and render them as they come in so users see text appearing in real-time. Once the stream finishes, if there's still a sentinel visible, the client fetches the next batch. The word counter keeps running throughout. I need to check what page.tsx currently does—it might already be server-rendering initial entries—and verify the AI Gateway setup. The Vercel AI Gateway supports zero-config for Google Vertex (where Gemini models live), so I'll try using it directly without an API key first, and request one if I hit a 401.b3:T88c,I'm thinking through a hybrid approach where the first chunk comes from a server-rendered corpus generator for instant content, then subsequent chunks stream from AI. I need to set up a new API route that accepts parameters for the starting entry number and topics to generate from. The route will use the streaming text model to generate about four encyclopedia entries in a specific markdown format with headings and paragraphs, then return the stream directly to the client. I'll seed the topic selection deterministically based on the entry number so the variation feels natural but reproducible. On the client side, I'm replacing the current loader with a streaming reader that fetches from this endpoint, decodes chunks progressively, and parses entries by splitting on heading markers. The component tracks completed entries and the current partial entry being streamed, numbering them sequentially and updating the word count in real time. Once the stream finishes, the IntersectionObserver will trigger the next fetch, and I need to handle the case where the sentinel is still visible by re-observing or auto-continuing the load. For parsing the streamed text, I'll keep it simple: buffer the incoming text, split by the heading delimiter, and treat the first line of each segment as the heading with the rest as paragraphs. The render logic will display finished entries as blocks and also render the in-progress partial entry from the current buffer. Entry numbering uses a ref that increments when each fetch completes, so during streaming the entries are numbered relative to the current batch start. For the word counter, I'll compute it during render from the finished and partial entries rather than maintaining it as separate state. On the error handling side, if the fetch fails I'll retry after a delay, but also keep the old generator as a fallback — the server route can catch errors and respond with deterministic generated text in the same format to ensure the stream never truly ends. To avoid repetition across requests, I'll pass a sequence number and derive topics from that using a long topics list, plus set temperature around 0.9.
