How Many Cat Breeds Are There in the World?

A visitor stands in an animal shelter. Dozens of eyes stare back — striped, jet-black, long-haired, completely bald. Almost everyone eventually asks the same question: how many cat breeds are there in the world? The answer is simple, and surprisingly complicated.

Feline registries — the professional organizations that classify domestic cats — officially recognize between roughly 40 and 70 cat breeds. The exact figure depends on the association. The Cat Fanciers’ Association (CFA) recognizes just over forty, while The International Cat Association (TICA) lists more than seventy.

And that’s only the official record. Outside the catalogues and competition rings, hundreds of regional lines, natural populations, and developing breeds also exist. New cat breeds continue to emerge today, evolving alongside humans.

How Many Cat Breeds Are There Today?

Ask a professional breeder or felinologist this question and the answer usually comes with a pause — not twenty, not a hundred. Today, roughly 45 to 73 recognized cat breeds appear in the major international registries. Why the variation? Each organization uses slightly different classification rules. Some recognize new breeds quickly once genetic stability is clear; others insist on long evaluation periods first.

Here is how the numbers typically look across the largest registries:

One detail matters here: the same breed can appear under slightly different standards depending on the registry, and similar regional variations are sometimes grouped under a single breed. That alone explains much of the confusion.

Another surprising fact: most domestic cats worldwide do not belong to any official breed. They are commonly called Domestic Shorthair or Domestic Longhair — natural populations rather than selectively developed breeds. Even so, classifications remain useful. A recognized breed gives owners reliable clues about temperament, coat type, grooming needs, and behavior.

How Scientists Classify the Different Types of Cats

There is an entire scientific field devoted to cats. It’s called felinology — the study of domestic cats, their genetics, breeding patterns, behavior, and physical structure.

Felinologists typically classify types of cats using several key criteria:

• coat length and texture
• color genetics
• body structure
• geographic origin
• unique mutations affecting fur or bone structure

Genetics plays the central role. A single mutation can completely change the appearance of a cat, and many modern breeds appeared because someone noticed an unusual kitten and decided to develop the trait. For example:

• Scottish Fold developed from a mutation affecting cartilage in the ears.
• Sphynx, the famous hairless cat breed, emerged from a gene affecting hair-follicle development.
• Selkirk Rex, one of the rare curly-coated breeds, resulted from a mutation producing soft, wavy fur.

What makes feline genetics so interesting is how often these traits appear spontaneously. A curly-coated kitten may show up in an otherwise normal litter; a hairless kitten can be born to two fully coated parents. When breeders recognize such traits, they sometimes build entirely new breeds around them.

The Biggest Cat Breed and Other Giant Domestic Cats

Some people want a cat. Others want something slightly more dramatic — a feline that looks almost like a small wild predator. That’s where the Maine Coon enters the conversation.

The Maine Coon is widely considered the biggest domestic cat breed. Adult males frequently weigh 8 to 11 kilograms, and some grow even larger; their bodies can stretch close to a meter from nose to tail. The breed developed naturally in the cold climate of Maine, evolving several useful adaptations over generations:

• thick, water-resistant coats
• large paws for walking on snow
• powerful bone structure
• long, bushy tails for warmth

It is not the only giant, however. Other big cat breeds include:

• Norwegian Forest Cat
• Ragdoll
• Siberian Cat
• Savannah

The Savannah is especially unusual: a hybrid between a domestic cat and the African serval, a wild species. Some Savannahs reach 12–14 kilograms and stand surprisingly tall for a house pet, often resembling a miniature cheetah.

Hairless Cat Breeds: Understanding the Genetics

Hairless cats tend to surprise people. Their skin appears wrinkled, their ears look oversized, and their bodies feel unusually warm to the touch. The most famous example is the Sphynx, perhaps the best-known hairless cat breed.

An interesting detail: Sphynx cats are not completely bald. They actually carry a very fine layer of fuzz known as vellus hair — similar to the soft, peach-like fuzz on human skin. The genetic mechanism behind hairlessness involves a mutation that affects hair-follicle formation; the follicles still exist, but they produce extremely short, fragile hairs.

Several other hairless breeds developed independently:

• Donskoy
• Peterbald
• Ukrainian Levkoy

Each of these breeds appeared in different regions and through different mutations, yet they share a similar appearance — one of the clearest examples of how genetic variation creates entirely new types of cats.

Curly Cat Breeds: The Rare Rex Cats

Curly fur in cats is extremely rare. When it appears, breeders often refer to the resulting animals as Rex cats, a term used for genetic mutations that affect coat structure. Instead of typical straight fur, the hairs grow in twisted or wavy patterns.

Several well-known curly cat breeds belong to this group:

• Devon Rex
• Cornish Rex
• Selkirk Rex
• LaPerm

Each has a slightly different genetic cause behind the curls. The Selkirk Rex carries a dominant gene for the curly coat, so kittens only need one copy of the gene to display the trait. The Cornish Rex and Devon Rex, by contrast, rely on different recessive mutations. The result is cats with coats that look almost like soft clouds — widely regarded as some of the most charming in the feline world.

What Breed Is a Tabby Cat?

This is one of the most common misunderstandings among cat owners: a tabby cat is not a breed. The word “tabby” refers to a coat pattern, not a genetic lineage.

The classic tabby pattern usually includes:

• stripes along the body
• swirls or marbled markings
• rings on the tail
• a distinctive “M” shape on the forehead

These markings appear across dozens of cat breeds, including the Maine Coon, American Shorthair, Bengal, British Shorthair, and Siberian. So when someone asks “what breed is a tabby cat?”, the correct answer is straightforward: tabby describes the pattern, not the breed itself.

What Cat Breeds Are Hypoallergenic?

Many people searching for a new pet wonder which cat breeds are hypoallergenic. The idea sounds appealing — a cat that doesn’t trigger allergies — but the science is more complicated.

Most allergic reactions to cats are caused by a protein called Fel d 1, which is produced in saliva and skin glands. When cats groom themselves, the protein spreads onto the fur and eventually into the air. Some breeds appear to produce lower levels of Fel d 1, including:

• Siberian
• Balinese
• Devon Rex
• Cornish Rex
• Sphynx

Does this guarantee that allergy sufferers will have no reaction? Unfortunately, no — but many people report milder symptoms with these breeds compared to others.

The Most Common Cat Breeds in the World

Popularity among cat breeds shifts over time. Cultural trends, films, social media, and breeding programs all influence public taste. Even so, several breeds consistently rank among the most common cat breeds worldwide:

1. Persian
2. Maine Coon
3. Ragdoll
4. British Shorthair
5. Siamese
6. Bengal

The British Shorthair, for example, became famous for its plush coat, round face, and calm personality. Internet culture played its part too — photos of these cats spread widely online, reinforcing their reputation as some of the most irresistibly cute breeds.

The Most Expensive Cat Breed

Prices for cats vary widely. Adoption fees from shelters might come to less than a hundred dollars, while pedigreed kittens from professional breeders can reach thousands. Among the most expensive cat breeds, one consistently appears at the top: the Savannah.

Typical price ranges include:

Savannah cats are expensive largely because of their hybrid origin: breeding them requires careful genetic management and specialized knowledge. Their wild appearance also drives strong demand.

The Best Cat Breeds for Families

Choosing the best cat breed often depends on lifestyle rather than appearance. Families with children usually prefer breeds known for patience, gentle behavior, and adaptability. Several frequently appear on recommendations for households:

• Ragdoll — calm, affectionate, and tolerant
• Maine Coon — friendly and playful
• British Shorthair — balanced temperament
• Birman — highly social
• Siberian — energetic yet affectionate

These breeds tend to integrate well into family environments, interacting easily with children and adapting to daily household activity.

Black Cat Breeds: Myths and Reality

Black cats have a long history in human culture. In medieval Europe they were sometimes linked with superstition; today, they have gained strong popularity among cat lovers.

The phrase “black cat breed” can be slightly misleading, because many breeds are capable of producing solid black coats — including the Bombay, Persian, British Shorthair, and Maine Coon. The Bombay was specifically developed to resemble a miniature panther, and its glossy black coat and copper eyes create the effect remarkably well.

Cute Cats: Why Certain Breeds Look Irresistible

People often describe kittens simply as “cute cats.” But what actually makes a cat look cute? Behavioral scientists studying animal perception often refer to the baby schema effect — a set of physical traits that humans instinctively perceive as adorable, including:

• large, round eyes
• short noses
• round faces
• soft fur

Several breeds display these features strongly, among them the Persian, Scottish Fold, British Shorthair, and Ragdoll. These traits trigger nurturing instincts in humans — one reason cats became such successful companion animals.

The world of cats is far richer than most people imagine. Breeds emerge, evolve, and occasionally disappear; genetics, selective breeding, and spontaneous mutations all contribute to this diversity. Today, international organizations recognize several dozen cat breeds, and tomorrow that number may grow.

Whether someone is fascinated by the largest cat breed, intrigued by a mysterious hairless cat breed, or simply searching for a cute companion to share their home with, one truth remains clear: cats have mastered the art of living beside humans — and they continue to surprise us.
