Cats are among the most intriguing species in the animal kingdom, belonging to a well-defined scientific classification that helps researchers, pet owners, and breeders understand their origins, relationships, and evolution.
This guide explores the taxonomy of cats, covering everything from binomial nomenclature to the phylum, genus, and species classification. A detailed cat taxonomy chart is included for clarity.
Cats are one of the most beloved and widespread domesticated animals, but their scientific classification reveals a deeper connection to the wild. As members of the Felidae family, domestic cats share an evolutionary lineage with big cats like lions and tigers. Understanding their taxonomy helps explain their behaviors, instincts, and biological characteristics.
Below is a detailed classification of the domestic cat (Felis catus), illustrating its place within the animal kingdom.
The table below outlines the hierarchical classification of the domestic cat (Felis catus) according to modern taxonomic standards.
| Taxonomic Rank | Classification |
| Kingdom | Animalia (Animals) |
| Phylum | Chordata (Vertebrates) |
| Class | Mammalia (Mammals) |
| Order | Carnivora (Carnivores) |
| Family | Felidae (Cats) |
| Genus | Felis (Small wildcats & domestic cats) |
| Species | Felis catus (Domestic cat) |
This classification system places house cats within the broader animal kingdom, showing their evolutionary connections with wild cats and larger feline relatives.
Cats belong to the Animalia kingdom, which includes all animals. This means they are multicellular, rely on other organisms for food (heterotrophic), and have cells without cell walls. Unlike plants, animals exhibit movement and complex behaviors, traits that are evident in cats.
The Chordata phylum includes animals that have a notochord (a flexible rod supporting the body) at some stage of development. Cats belong to this group because they have a spinal cord and backbone, which are essential for their agility and movement.
As mammals, cats share key traits such as:
The order Carnivora consists of meat-eating mammals, including cats, dogs, bears, and weasels. Cats are obligate carnivores, meaning they require a diet primarily made of meat. Their sharp teeth, retractable claws, and keen senses make them excellent hunters.
The Felidae family includes all cats, from tiny domestic breeds to large wild species like lions and tigers. Key characteristics of this family include:

The Felis genus consists of small wildcats and domestic cats. Unlike their larger relatives in the Panthera genus (lions, tigers, leopards), members of the Felis genus typically:
The domestic cat (Felis catus) has adapted to living alongside humans for thousands of years. Though they retain their hunting instincts, they have been selectively bred for different appearances, temperaments, and behaviors. Domestic cats exhibit:
Domestic cats belong to the phylum Chordata, which includes all vertebrates—animals with a backbone and spinal cord. This category also encompasses mammals, birds, reptiles, amphibians, and fish.
A defining feature of Chordata is the presence of a notochord (a flexible rod-like structure) during embryonic development, which later forms the spinal column in vertebrates.

The classification of a cat follows the standard hierarchical structure used in biology. Below are the seven primary taxonomic ranks and their definitions:
Kingdom – Animalia
Phylum – Chordata
Class – Mammalia
Order – Carnivora
Family – Felidae
Genus – Felis
Species – Felis catus
This hierarchical structure helps classify domestic cats based on shared characteristics with wild felines and other carnivorous mammals.
The binomial nomenclature system, developed by Carl Linnaeus, assigns a two-part scientific name to every species. For domestic cats, this name is:
Felis catus
This naming system ensures universal consistency when identifying cats in scientific research and classification studies.
The Latin name for a house cat is Felis catus. Some taxonomic classifications refer to it as Felis silvestris catus, recognizing domestic cats as a subspecies of the wildcat (Felis silvestris).
Key Distinction:
Yes, cats belong to the Felidae family, which classifies them as felines. This family includes both small and large wild cats, such as:
✅ Big Cats (Panthera genus) – Lions, tigers, leopards, and jaguars.
✅ Smaller Wild Cats (Felis genus) – Wildcats, sand cats, and domestic cats.
As felines, domestic cats share characteristics with larger relatives, including:
✔ Retractable claws for hunting and climbing.
✔ Sharp teeth suited for carnivorous diets.
✔ Keen senses of hearing, vision, and smell.
Cats are part of the Felidae family, a group of carnivorous mammals known for agility, hunting skills, and solitary nature. This family includes:
🔹 Big Cats (Panthera genus) – Tigers, lions, leopards, and jaguars, which possess the ability to roar.
🔹 Small to Medium-Sized Cats (Felis genus) – Wildcats, sand cats, and domestic cats, which purr but do not roar.
Domestic cats are closely related to several species within the Felidae family, including:
Yes, cats are vertebrates, meaning they have a backbone and spinal column. This places them in the phylum Chordata, alongside other mammals, birds, reptiles, and amphibians.
The taxonomy of cats has evolved due to advancements in:
🔹 DNA Analysis – Genetic research has helped refine species relationships.
🔹 Fossil Discoveries – New evidence has clarified the ancestry of felines.
🔹 Conservation Efforts – Improved classification helps identify subspecies for protection.
Historically, domestic cats were classified under Felis silvestris catus, grouping them with wildcats. However, modern genetic studies support their classification as a distinct species: Felis catus.
For example, the American domestic shorthair cat taxonomy aligns with Felis catus, but some older classifications linked it to wildcat ancestry.
The table below highlights the key differences between domestic cats and wildcats (Felis silvestris).
| Feature | Domestic Cat (Felis catus) | Wildcat (Felis silvestris) |
| Habitat | Homes, urban areas | Forests, savannas, mountains |
| Domestication | Fully domesticated | Wild, with some hybrid species |
| Genetics | Selective breeding | Natural selection |
| Behavior | Social and adaptable | Solitary and territorial |
Despite their differences, domestic cats and wildcats share a common evolutionary lineage.
Understanding the classification of domestic cats (Felis catus) helps us see their place in the animal kingdom and their evolutionary ties to wild felines. Below is a detailed breakdown of their scientific classification.
Cats belong to the biological order Carnivora, a diverse group of mammals primarily adapted for meat consumption. This order includes several families, each with distinct adaptations for hunting and survival.
The Felidae family includes both big cats and small wildcats, all of which are obligate carnivores, meaning they must eat meat to survive.
✅ Examples:
✔ Key Adaptations:
Domestic cats (Felis catus) share many predatory traits with their wild relatives, even though they rely on humans for food.
The Canidae family consists of social carnivores and omnivores that are often adapted for endurance hunting rather than stealth.
✅ Examples:
✔ Key Adaptations:
Unlike cats, dogs are facultative carnivores, meaning they can survive on plant-based foods but thrive on a meat-heavy diet.
Bears are large mammals that belong to the Ursidae family. While classified under Carnivora, most bear species are omnivores, eating both meat and plant-based foods.
✅ Examples:
✔ Key Adaptations:
While some bears are opportunistic hunters, they do not rely on meat as heavily as cats or dogs.
Raccoons and their relatives belong to the Procyonidae family, which includes small to medium-sized mammals with adaptations for scavenging.
Examples:
✔ Key Adaptations:
Unlike true carnivores, raccoons and their relatives have varied diets, eating insects, fruits, and small vertebrates.
All members of Carnivora share certain evolutionary traits that make them effective hunters or opportunistic feeders:
✔ Specialized Teeth – Sharp canine teeth and carnassials designed for slicing meat.
✔ Strong Jaw Muscles – Allow for powerful bites, essential for hunting.
✔ Enhanced Senses – Acute smell, night vision, and hearing to detect prey.
While some carnivores (bears and raccoons) have adapted to omnivorous diets, cats remain obligate carnivores.
Unlike other members of Carnivora, domestic cats require meat-based diets for survival due to their unique metabolic needs.
✔ Taurine – Essential for heart health, vision, and reproduction.
✔ Arginine – Required to detoxify ammonia from their body.
✔ High-Protein Metabolism – Cats lack certain enzymes to efficiently process carbohydrates, making meat their primary energy source.
Because of these dietary needs, cats cannot be sustained on plant-based diets and must consume animal protein for optimal health.
Unlike omnivores, cats lack certain digestive enzymes needed to process plant-based food efficiently.
In biological classification, domestic cats belong to the:
The binomial nomenclature of cats places them within the same genus as wildcats (Felis silvestris), reinforcing their close genetic relationship. Scientists sometimes classify domestic cats as a subspecies of the wildcat, referring to them as Felis silvestris catus.
This classification highlights how domestic cats still share many traits with their wild ancestors, including their hunting instincts, agility, and solitary nature.
Cats have a long and fascinating evolutionary history, dating back millions of years. Unlike many domesticated animals, which were bred for specific purposes, cats played an active role in their own domestication. From wild hunters to beloved companions, their journey is a unique blend of adaptation and mutual benefit with humans.
Domestic cats trace their ancestry back to the African wildcat (Felis lybica), which was domesticated nearly 9,000 years ago in the Middle East.
Unlike dogs, which were bred for specific tasks, cats largely domesticated themselves by forming symbiotic relationships with humans.
Domestic cats share many traits with big cats but differ in size, behavior, and vocalization.
| Feature | Domestic Cat (Felis catus) | Big Cats (Panthera genus) |
| Size | 8–16 inches tall | Can exceed 4 feet in height |
| Vocalization | Purrs but cannot roar | Roars but cannot purr |
| Social Behavior | Solitary but adaptable | More social (lions) or solitary (tigers) |
| Hunting Style | Small prey, stalking | Large prey, ambush predators |
Despite their size differences, both groups share keen hunting instincts, retractable claws, and exceptional night vision.
Domestic cats (Felis catus) are agile, adaptable, and well-suited for both hunting and companionship. Their physical traits, including a flexible skeletal structure, sharp teeth, and retractable claws, contribute to their efficiency as predators. Understanding these characteristics provides insight into their survival instincts and natural behaviors.
Domestic cats (Felis catus) are known for their unique behavioral traits, including territoriality, grooming, and social interactions. Their keen senses, long tails, and specialized hunting adaptations make them efficient predators. Understanding their behavior helps deepen our appreciation of these fascinating companions.

✔ Gives birth to live young.
✔ Produces milk for its offspring.
Cats belong to the Felidae family, which includes both big cats (lions, tigers, leopards) and small wildcats (wildcats, sand cats, and domestic cats).
The scientific classification of a domestic cat follows this hierarchy:
The binomial nomenclature of a cat is Felis catus, where:
Domestic cats are closely related to:
✔ Wildcats (Felis lybica) – Their direct ancestor.
✔ Cheetahs (Acinonyx jubatus) – Unique among felines for speed.
✔ Cougars (Puma concolor) – Large cats, not classified as "big cats.”
| Feature | Domestic Cat (Felis catus) | Wildcat (Felis silvestris) |
| Habitat | Homes, urban areas | Forests, savannas, mountains |
| Domestication | Fully domesticated | Wild, some hybrid species |
| Behavior | Social and adaptable | Solitary and territorial |
Domestic cats retain many wildcat instincts, but they are genetically adapted for coexistence with humans.
Yes, a cat is a vertebrate because it has a backbone and spinal cord, placing it in the phylum Chordata.
Cats belong to the order Carnivora, which includes other meat-eating mammals such as:
✔ Dogs (Canidae family)
✔ Bears (Ursidae family)
✔ Raccoons (Procyonidae family)
No, domestic cats (Felis catus) cannot breed with big cats (lions, tigers, leopards) due to genetic differences and chromosome mismatches. However, domestic cats can hybridize with certain wildcat species, such as:
✔ Bengal cats (Domestic cat × Asian leopard cat).
✔ Savannah cats (Domestic cat × Serval).
The average size of a domestic cat varies, but general measurements include:
Larger breeds, like the Maine Coon, can weigh over 20 lbs (9 kg).
Domestic cats evolved from the African wildcat (Felis lybica), which was domesticated around 9,000 years ago in the Middle East. Unlike dogs, which were selectively bred by humans, cats domesticated themselves by forming a mutually beneficial relationship with early human civilizations.
Yes, but with challenges. Feral domestic cats retain hunting instincts, but they lack the adaptations for survival in extreme conditions, unlike true wildcats.
The ability to roar or purr is determined by differences in the hyoid bone structure in the throat.
✔ Domestic Cats (Felis catus) – Can purr but cannot roar.
✔ Big Cats (Panthera genus) – Can roar but cannot purr (except cheetahs).
This is due to differences in larynx flexibility and vocal cord structure.
