You’ve probably seen one darting under a parked car or lounging on a neighbor's porch. A black and white striped cat. At first glance, you might just call it a "tabby" and move on with your day. But if you look closer, the genetics behind that coat are actually pretty wild. It's not just a random splash of paint. There is a specific biological "war" happening on that cat's skin between two different sets of instructions.
Most people get the terminology wrong. Honestly, it’s understandable. We use words like "tuxedo," "tabby," and "piebald" interchangeably, but they mean very different things to a vet or a geneticist. When you see a cat with black stripes on a white background—or white patches over a black striped body—you're looking at the interplay of the Agouti gene and the White Spotting gene.
It’s complex. It’s messy. And it’s why no two of these cats look exactly the same.
The "Grey" Area of the Black and White Striped Cat
First, let's clear up a massive misconception. Technically, a "pure" black and white striped cat—where the stripes themselves are jet black and the "background" is snow white—doesn't exist in the way most people think.
In the world of feline genetics, stripes (tabby patterns) occur on the "ground color" of the hair. Usually, that ground color is a warm grey, agouti brown, or cinnamon. When you see a black and white striped cat, what you’re usually seeing is a silver tabby with high contrast, or a "patched" tabby.
The Silver Tabby Illusion
Some cats look like they stepped out of a noir film. This is often due to the Inhibitor gene (I). This gene suppresses the phaeomelanin (the yellow/red pigment) in the hair shaft.
- The result?
- The "background" of the stripes turns a sparkling, clear silver.
- The stripes remain a deep, dark black.
- From five feet away, it looks like a white cat with black zebra stripes.
It’s striking. It’s also the hallmark of the American Shorthair breed, specifically the "Silver Classic Tabby" variant. According to the Cat Fanciers' Association (CFA), this is one of the most recognizable and popular show patterns. If your cat looks like a literal silver dollar, this is likely what’s going on.
Why Some Cats Have White Socks and Striped Backs
Then there’s the "Piebald" factor. This is where things get really weird.
The White Spotting gene (S) is an incomplete dominant gene. Think of it like a bottle of white primer spilled over a finished painting. The cat's "true" coat might be a black mackerel tabby (the one with the "fishbone" stripes), but the White Spotting gene prevents pigment from reaching certain areas of the body during embryonic development.

Typically, the white starts at the "ends" of the cat—the paws, the chest, the tip of the tail—and moves upward. This is why you see so many striped cats with white "mittens" or a white "locket" on their chest.
If the white spotting is "high grade," you end up with a cat that is mostly white with just a few patches of black stripes on the head or tail. This is often called the Van pattern.
Basically, the cat is a striped cat wearing a very large, very irregular white coat.
The Mackerel vs. The Classic
Stripes aren't just stripes.
- Mackerel Tabbies: These have narrow stripes running vertically down the body. They look like little tigers. This is the "wild type" or ancestral pattern.
- Classic Tabbies: These have bold, swirling patterns that look like a marble cake.
When you mix these with white patches, the visual can be chaotic. You might have a cat with a perfectly white face but a "marble cake" of black and grey stripes across its hips. It’s a genetic lottery.
The "M" on the Forehead
Every black and white striped cat with tabby markings will have a distinct "M" shape on its forehead.
There are a lot of myths about this. Some people point to Ancient Egypt and the "Mau" (the Egyptian word for cat). Others mention Islamic folklore involving the Prophet Muhammad. In reality, it’s just how the tabby gene manifests on the facial skin. The hairs on the forehead are shorter and the pigment density increases at those specific tension points during skin development.
It’s a biological stamp. If the cat has stripes, it has the M. If you can't see the M because the forehead is solid white, the gene is still there—it’s just "masked" by the lack of pigment.

Health, Temperament, and the "Cat-titude" Myth
Does the color matter for how the cat acts?
Honestly, probably not.
People love to swear that "torties" have "tortitude" or that orange cats share a single brain cell. When it comes to the black and white striped cat, many owners report a high level of intelligence and "dog-like" loyalty. However, science is skeptical.
A study published in the Journal of Applied Animal Welfare Science surveyed over 1,200 cat owners to see if coat color linked to aggression. While some owners reported higher "irritability" in certain colors, the data suggests these are mostly human biases. We see a bold pattern and assume a bold personality.
That said, there is one health thing to watch for.
If your black and white striped cat is mostly white—especially around the ears—they are much more prone to Squamous Cell Carcinoma (SCC). This is a form of skin cancer. Because the skin under white fur lacks protective melanin, the sun can do some serious damage.
If your cat likes to sunbathe in the window, and their ears are white with black stripes nearby, keep an eye on the edges of the ears. Any crusting or redness that doesn't go away needs a vet's eyes immediately.
Breeding and Rarity
You don't just "find" a perfectly symmetrical black and white striped cat every day. In the wild, or in "community cat" populations, colors tend to blend. You get "muddier" browns and greys because those provide better camouflage.
The high-contrast black and white look is often a result of selective breeding or just a very lucky roll of the genetic dice in a domestic setting.
Common Breeds with this Pattern:
- American Shorthair: The gold standard for the silver/black stripe look.
- Maine Coon: These giants often have "tabby with white" patterns that look incredibly rugged.
- European Shorthair: Very common in the UK and Europe, often with the "mackerel" stripe style.
- Scottish Fold: Their folded ears combined with a striped-and-white face makes them look like little owls.
How to Care for the Coat
Interestingly, the texture of the hair can change based on the color.
Black hairs are often slightly coarser because they are packed with more eumelanin. White hairs can feel softer or "downier" because they are essentially hollow tubes of protein without pigment.
If you have a black and white striped cat, you might notice they shed differently. The white hairs show up on your black jeans. The black hairs show up on your white rug. It’s a lose-lose situation for your vacuum cleaner.
Brushing is non-negotiable. Even shorthaired cats benefit from a weekly session with a slicker brush. It distributes the skin oils (sebum) across the hair, which makes those black stripes really "pop" and look glossy. A dull coat on a striped cat often means they aren't getting enough Omega-3 fatty acids in their diet.
The Mystery of the "Ticked" Stripe
Sometimes a cat looks like it should be striped, but the pattern is blurry. This is called "ticking."
Each individual hair has multiple bands of color on it. If your cat is a black and white striped cat but the stripes look "faded" or "sandy," they likely have the Abyssinian gene or some variation of it. It’s less like a tiger and more like a cougar.
When you add white patches to a ticked coat, the cat can look almost "salt and peppered." It’s rare, but it’s a favorite among breeders for its subtle, sophisticated look.
Final Practical Steps for Owners
If you’re lucky enough to share your home with one of these striking animals, there are a few things you should do to keep them healthy and their coat looking sharp.
First, check the skin. Because the contrast is so high, it's actually easier to spot fleas or skin irritations on the white parts of the cat. Use this to your advantage during your weekly grooming sessions.
Second, mind the sun. As mentioned, those white ears are a sun-trap. If your cat is a heavy sun-worshipper, consider getting a UV-blocking film for your windows. It saves your furniture and your cat’s ears.
Third, diet matters. To maintain the deep black of the stripes, the cat needs an amino acid called Tyrosine. Tyrosine is a precursor to melanin. If a cat is deficient in certain nutrients, their black stripes can actually start to turn a rusty, brownish color. This is often called "rusting." If your black-striped cat is looking a bit reddish-brown, it might be time to look at the protein quality in their kibble.
At the end of the day, a black and white striped cat is a masterpiece of natural engineering. Whether it's a "classic" swirl or a "mackerel" dash, those patterns are a window into the cat’s DNA history. They aren't just pets; they're walking, purring genetic puzzles.
Keep them brushed, keep them out of the harsh midday sun, and make sure their protein intake is high. The rest is just enjoying the view of one of nature's most iconic patterns.
