What Color Were Cats Originally? Tracing Feline Ancestry
The original color of cats was likely a muted brown tabby pattern, providing excellent camouflage in their ancestral wild environments; however, understanding the complete answer to what color were cats originally requires delving into genetics and evolutionary history.
Introduction: The Feline Palette and Its Origins
The modern domestic cat, Felis catus, exhibits a remarkable diversity of coat colors and patterns. From sleek black panthers to calico queens, the range seems endless. But what color were cats originally? Unraveling this question takes us back to the wild ancestors of our feline companions, where survival depended on camouflage and adaptation. The genetic makeup responsible for today’s colors is a testament to millennia of evolution and, more recently, selective breeding by humans.
The African Wildcat: The Prime Suspect
The prevailing scientific consensus points to the African wildcat (Felis silvestris lybica) as the primary ancestor of domestic cats. These wildcats, found across Africa and parts of the Middle East, possess a characteristic coat pattern: a brown tabby. This is a crucial clue in determining what color were cats originally.
- The tabby pattern, marked by stripes, swirls, or spots, provides excellent camouflage in grassy and wooded environments.
- This pattern is not a single gene but a complex interplay of genes that control pigment production and distribution.
Genetics of Cat Coloration: A Brief Overview
Understanding what color were cats originally also requires a basic understanding of feline genetics. Coat color is determined by several genes, each with multiple alleles (variations).
- Agouti Gene (A/a): Determines whether a cat’s hairs have a banded (agouti) or solid (non-agouti) appearance. Agouti allows the tabby pattern to be visible.
- Tabby Gene (T/t): Controls the type of tabby pattern (mackerel, classic, spotted, ticked).
- Orange Gene (O/o): Located on the X chromosome, this gene controls the production of phaeomelanin (red/orange pigment). Females need two copies of the ‘O’ allele to be orange.
- Dilute Gene (D/d): Affects the intensity of pigment. The ‘d’ allele dilutes black to blue (gray) and orange to cream.
- Extension Gene (E/e): Impacts the distribution of eumelanin (black/brown pigment).
These are just a few of the key genes involved. Mutations in these and other genes are responsible for the wide array of colors and patterns we see in domestic cats today.
The Role of Domestication: Expanding the Color Palette
While the African wildcat likely sported a brown tabby coat, domestication played a significant role in diversifying the feline color palette.
- As cats moved into human settlements, natural selection pressures shifted.
- Mutations that might have been detrimental in the wild (e.g., striking colors that made cats more visible to predators) became less of a concern.
- Humans, consciously or unconsciously, began selecting for cats with desirable traits, including unique colors and patterns.
Selective breeding, particularly in the last few centuries, has resulted in the stunning variety of coat colors we admire today. This reinforces the idea that what color were cats originally, while likely brown tabby, is far from the only option available in the modern feline population.
Environmental Adaptation: A Driving Force
Beyond domestication, environmental adaptation also influenced cat coloration.
- Cats living in colder climates might benefit from thicker coats and lighter colors for better camouflage in snowy environments.
- Cats living in darker environments might develop darker coats for better concealment.

Frequently Asked Questions (FAQs)
What is the most common cat color in the wild today?
The most common cat color in wild or feral cat populations is still typically some variation of tabby, providing effective camouflage. The specific shade and pattern will vary depending on the local environment.
Are there any breeds of cats that are considered to be “original” colors?
While no breed perfectly replicates the exact appearance of the African wildcat, breeds like the Egyptian Mau and the Abyssinian, with their ticked tabby patterns, are often cited as having coloration reminiscent of their wild ancestors. These breeds have retained some of the ancestral traits.
How did black cats evolve?
Black cats owe their color to a mutation in the non-agouti gene (a/a). This mutation suppresses the agouti pattern, resulting in a solid black coat. While the origin is not certain, it likely arose as a spontaneous mutation that was either advantageous or neutral.
What’s the difference between a tabby cat and a striped cat?
“Tabby” is a pattern, not a color. A tabby cat can be any color (e.g., brown, gray, orange) but will exhibit one of the tabby patterns: mackerel (striped), classic (swirled), spotted, or ticked. “Striped” usually refers specifically to the mackerel tabby pattern.
Is there such a thing as a naturally occurring white cat?
Yes, naturally occurring white cats exist. The most common cause is the dominant white gene (W), which masks all other color genes. Another cause is albinism, which is a genetic condition that results in a complete lack of pigment.
Do coat colors affect a cat’s personality?
While there are anecdotal reports of certain coat colors being associated with specific personality traits (e.g., orange cats being “friendlier”), there is little scientific evidence to support this claim. Personality is more likely influenced by genetics, socialization, and environment.
How does the orange gene work in cats?
The orange gene (O) is located on the X chromosome. Female cats have two X chromosomes (XX), so they can be either orange (OO), black (oo), or calico/tortoiseshell (Oo). Male cats have one X and one Y chromosome (XY), so they can only be orange (O) or black (o).
What role does melanin play in cat coat color?
Melanin is the pigment responsible for most of a cat’s coat color. There are two main types of melanin: eumelanin (black/brown) and phaeomelanin (red/orange). The amount and distribution of these pigments determine the final coat color.
Why are calico cats almost always female?
Calico cats are almost always female because the orange gene, which determines whether a cat will display orange or black fur, is located on the X chromosome. Female cats have two X chromosomes and can therefore express both orange and black fur, resulting in the calico pattern. Males only have one X chromosome, so they can only be one color.
Can coat color affect a cat’s health?
Yes, in some cases, certain coat colors are associated with specific health conditions. For example, white cats with blue eyes are more likely to be deaf. However, these associations are relatively rare.
What is a “dilute” cat color?
A dilute cat color refers to a lighter shade of a base color. This is caused by the dilute gene (d/d), which dilutes black to blue (gray) and orange to cream.
How has selective breeding impacted feline coat colors?
Selective breeding has dramatically expanded the range of feline coat colors and patterns. Breeders have intentionally selected for cats with desirable traits, leading to the development of new colors, patterns, and coat lengths. This has resulted in the diverse array of breeds we see today.
