What are tortoiseshell cats?

The term tortoiseshell doesn't refer to a breed but to a coat color pattern. They are often referred to as torties, and the tortoiseshell name comes from their mottled appearance, with patches of tortoiseshell and speckles and streaks of orange, red, and black. 

Physical characteristics

Tortoiseshell cats usually have:

• a blended, marbled coat of black or chocolate mixed with cream or orange

• varied patterns, such as heavily mixed (bridled) to patchier versions

• little or no white fur

• long or short hair

Breeds that commonly have tortoiseshell patterns

Many purebreds have tortoiseshell coloring as one of their types, including:

• American Shorthair 

• British Shorthair

• Persian

• Maine Coon

• Cornish Rex

• Devon Rex

• Oriental Shorthair

• Japanese Bobtail

• Sphinx

Persians and Maine Coons with their long hair have especially stunning tortoiseshell coats.

Personality traits

The temperament of a tortoiseshell cat is often referred to as a “tortitude”. Traits that lead to that include: 

• independence

• vocal or expressive behavior

• spunk or feistiness

• strong loyalty to one person

• strong opinions and playfulness

While it's not based on scientific research, people often describe torties as spirited and full of character.

It’s a little more complicated than that.

What are calico cats? 

Just like tortoiseshells, calico is not a breed, but a coat pattern. Calico cats have a patchy look that’s comprised of black, orange, and white.

Physical characteristics

Calico cats usually have:

• three colors: black or gray, orange or cream, and white

• a predominantly white base, which really sets them apart from tortoiseshells

• large, distinct patches of color

• variations such as calico, dilute calico, and calico plus tabby (caliby)

Like torties, most calicos are female.

Many purebred cats have the calico pattern among their coat colors. These include:

• American Shorthair

• Persian

• Maine Coon

• Japanese Bobtail

• Norwegian Forest 

• Scottish Fold

• Manx

• Turkish Van

• Oriental Shorthair

• British Shorthair

Of particular interest are calico Persians and calico Japanese Bobtails due to their striking appearance.

Personality traits

Calicos are often described as:

• energetic and playful

• sweet but sassy

• strong-willed

• independent but affectionate

In other words, calicos are lively and full of personality.

Differences between tortoiseshell and calico cats

The two types of cats share similar genetics, but their coat patterns differ:

Coat pattern and color distribution

• Tortoiseshell: black and orange with little or no white

• Calico: definite patches of black, orange, and white

Appearance

• The amount of white in a calico’s coat makes it appear brighter, while tortoiseshells appear richer, darker, and more marbled.

Pattern predictability

• Calicos are more consistent in their appearance and more recognizable. Torties are highly variable. They have many different patterns.

Similarities between tortoiseshell and calico cats

Genetics

Because the genes that create black and orange fur are located on the X chromosome, almost all tortoiseshell and calico cats are female. Female cats have two X chromosomes (XX), which means they can show both colors—one X may carry the black gene, while the other carries the orange gene. When their bodies switch between using each X chromosome, the coat ends up with a mix of black and orange patches.

Male cats usually have one X and one Y chromosome (XY), so they can show either black or orange, but not both. This is why male tortoiseshells and calicos are so rare.

To have both colors, a male must have an extra X chromosome—XXY—which is an uncommon genetic condition. These rare males almost always end up sterile, which is why a male calico or tortoiseshell is considered a true genetic rarity.

Not breed specific

Many breeds, such as Persians, Maine Coons, British Shorthairs, Japanese Bobtails, and Oriental Shorthairs, have cats of both patterns.

Personality reputation

Both tortoiseshell and calico cats have a long-standing reputation for being bold, spunky, and full of attitude. Many cat owners describe them as having a little extra “spark” compared to other cats. This isn’t something proven by science, but it’s a widespread observation among cat lovers, veterinarians, and breeders.

People often say torties and calicos are:

• Confident and expressive

• Quick to let you know what they want

• Energetic and playful

• Affectionate, but on their own terms

Some owners call it “tortitude” or “calico sass,” and while every cat is different, it’s easy to see why these patterns have developed such a strong personality legend. Their bright, vibrant coats combined with their spirited behavior make them unforgettable companions. Even though genetics don’t determine personality, many people feel these colorful cats come with colorful attitudes to match.

Health profiles

Fortunately, there are no known associations with health conditions and coat colors and patterns. Health conditions tend to be more associated with breed than with coat patterns.

Frequency

• Both types of cats are common, but torties with no white tend to be less common.

Terminology

• Tortoiseshell plus a tabby striping is referred to as a torbie.

• Calico with striping is referred to as a caliby.

Required care and maintenance for tortoiseshell vs calico cats

These tend to be the same in both types of cats. In terms of grooming, short-haired cats usually can get by with weekly brushing, while long-haired cats like Persians and Maine Coons need grooming several times a week.

Regarding nutrition, both need a high-quality, balanced diet with proper portion control and, of course, plenty of fresh water daily.

Exercise and enrichment requirements include daily play, climbing areas, scratching posts, and interactive toys such as puzzle feeders.

Veterinary care is similar for both. They need routine care that includes an annual exam or, depending on their age, semiannual exams, vaccinations, parasite prevention, dental care, and weight monitoring.

Behavioral support is needed because both torties and calicos tend to be bold and opinionated. Things like environmental enrichment and positive reinforcement can help you shape healthy behavior.

Do Calicos Really Have More ‘Cat-titude’ Than Other Cats?

More colors mean more spice, after all.

Choosing between a tortoiseshell and a calico cat

Visual preference

• If you like a marbled, blended color, choose a tortoiseshell.

• If you prefer a patchy, crisp, contrasted pattern, you may prefer a calico. 

• Breed and coat length depend entirely on your preferences because both patterns can be found in most breeds. 

Temperament 

• Similar, but different, stereotypes, again not scientific, have created the belief that torties have a bold tortitude while calicos are sweet but spicy.

You should choose based on the individual cat. More than coat pattern, a cat’s personality, health, and lifestyle compatibility should match what you're looking for.

Bottom Line

Tortoiseshell and calico cats are similar genetically but visually very different — torties appear blended black and orange, with almost no white. Calicos always have distinct white patches and patches of black and orange. Both are almost always female. It’s rare to find a male that’s tortoiseshell or calico. Both types can be found in many purebred and mixed breeds. The care is essentially identical across both patterns, and both are beautiful, expressive cats full of personality.
