“Tortitude” – The Unique Personality of Tortoiseshell Cats: Fact or Fiction?


Last updated August 2019

In August of 2009, I wrote a post titled Tortitude: The Unique Personality of Tortoiseshell Cats. The post describes some of the unique traits that many of these beautifully colored cats seem to share: they tend to be strong-willed, a bit hot-tempered, and they can be very possessive of their human. Other words used to describe torties are fiercely independent, feisty and unpredictable. They’re usually very talkative and make their presence and needs known with anything from a hiss to a meow to a strong purr.

The post still gets hundreds of views every single day, and has generated more than 14,000 comments to date. It has become more than just a source of information for cat lovers looking for more about cats with these distinct orange, tan and black colors: it has become a place for people to share stories about the torties in their lives.

As someone who has been owned by four torties at this point, not counting my first office cat at the animal hospital I managed, I feel that I’m somewhat of an expert on these special cats. And while Virginia, Amber, Buckley, Allegra and Ruby all had or have some degree of tortitude, their personalities were and are also very different. This appears to be true for the torties whose guardians have commented here on the site as well.


What is a tortoiseshell cat?

Contrary to what some people think, tortoiseshell cats are not a breed. They are named for their distinctive coloring – a combination of patches of black, brown, amber, red, cinnamon and chocolate. The size of the patches can range from a speckled pattern to large splotches of color. Tortoiseshell cats have have very few or no white markings, as opposed to calicos, who are tri-colored cats with larger areas of white fur. Sometimes, the colors are more muted. These torties are known as dilute torties. Very dark torties with a lot of black in their fur are often affectionately called “chocolate torties.” Occasionally, the typical tortoiseshell colors are also seen in a tabby (striped) pattern; these cats are referred to as “torbies.” Tortoiseshell is not a breed, the distinct markings appear in many different breeds.

The unique genetics of tortoiseshell cats

In addition to their unique personalities, torties also have unique genetics. A cat’s main color is determined by a primary coat color gene. The tortoiseshell pattern is determined by two co-dominant genes, in other words, two genes that are expressed at the same time and affect each other. In a bi-colored tortie, these two genes comingle to produce the characteristic brindled tortoiseshell pattern. In dilute torties, these genes are modified by a recessive gene, which results in softer coat colors. Black becomes grey, orange becomes cream.

The vast majority of tortoiseshell cats are female, because two X chromosomes are required to produce black, gold and orange coloring. Male cats only have one X and one Y chromosome, so technically it’s genetically almost impossible for a male to inherit the tortoiseshell coloring. A male tortoiseshell has an extra X chromosome, making it an XXY. According to a study by the College of Veterinary Medicine at the University of Missouri, only 1 in 3000 tortoiseshell cats is male.

A tortoiseshell cat may have a distinct tabby pattern on one of its colors. This pattern is driven by yet another gene. Tabby cats, also referred to as tiger cats, are cats with a coat featuring a pattern of distinctive stripes, lines, dots or swirling patterns. These cats are known as torbies, and, like all tortoiseshell cats, are predominantly female.


Tortoiseshell Cat Folklore

Tortoiseshell cats have a mythical folklore in many cultures, much of it centered around the rare male tortoiseshell. The Celts considered it a good omen if a male tortoiseshell stayed in their home.  English folklore has it that warts could be healed if rubbed by the tail of a male tortoiseshell’s tail during the month of May.  Japanese fishermen believed that male tortoiseshells protected their ships from storms and ghosts. A Khmer legend in South East Asia has it that the first tortoiseshell arose from the menstrual blood of a goddess born of a lotus flower.

Torties are thought to bring good luck in many cultures. They are sometimes referred to as the money cat.

Tortoiseshell cats were believed to have psychic abilities and see into the future. It is said that those who dream of a tortoiseshell cat will be lucky in love.

Are tortoiseshell cats really different from other cats?

Speaking from personal experience, it appears that no two tortoiseshell cats display the exact same amount of tortitude. Virginia had definitely read the book on tortitude. The first time I met her, during my interview for the hospital manager position, she greeted me by walking over to me, looking up at me, and then digging her claws into my legs to use them as a scratching post. Amber was the “anti-tortie” – she was a gentle, calm, almost shy cat, but she was a bit headstrong. Buckley’s tortitude manifested in her exuberance. She loved everything and everybody. Allegra is highly sensitive to the world around her, and often quick to react to something that she perceives as a threat. Ruby is the most high-spirited cat I’ve ever had. Of all my cats, she is the one with the highest dose of tortitude.


The experts weigh in on tortitude

I decided to check with some other experts to get their thoughts on tortitude. “I often tell clients that torties are the redheads of the cat world,” says feline veterinarian Dr. Fern Slack, who owns Uniquely Cats Veterinary Center in Boulder, CO. “They are beautiful, but short-tempered and quick to wrath. Of course they are not all like that, any more than every redhead is – but I always approach a tortie with a tad more circumspection than any other coat color.” While Dr. Slack takes a cautious approach to her tortie patients, she adds “I’ve always thought that the price you pay in tortitude, you get back tenfold in love.”

“There is no evidence that there is a link between color gene and personality,” says Dr. Elizabeth Colleran, a former president of the American Association of Feline Practitioners and owner of two cat hospitals, Chico Hospital for Cats in Chico, CA and the Cat Hospital of Portland in Portland, OR. “It is true though, that almost all tortoiseshell cats are females, and some people perceive females as being more headstrong than male cats. However, the real determination of personality is naturally a combination of genetics and environment.”

Jackson Galaxy has worked with his share of tortoiseshell cats in his decades of helping cats with behavioral challenges. “In my experience, tortitude is a very real thing,” says Jackson. “And now that there is a a study correlating coat pattern with behavior, our characterizations have been validated. Of course, anyone who knows me, knows I try not to talk about cats in generalities.” Jackson feels that torties and calicos are more energetically sensitive. “I think that’s part of the reason why their personalities are always on full display,” he says. “I’ve always said that cats are energetic sponges. Torties, however, just seem to soak up more, which is why they’ve got so much to say.”


Tortoiseshell cats are special

Those of us who love torties embrace their unique personalities. It is important to remember that every cat, regardless of coat color, is an individual. Not every tortie will exhibit the traits attributed to these beautifully colored cats, but the majority seem to live up to their reputation. As far as I’m concerned, tortitude is real. And while torties may, at times, seem like they have split personalities, going from purring away in your lap to suddenly racing around the house like a crazy kitten, those of us who love them wouldn’t want them any other way.

    I love my Missy cat so much. She is a tortie. My vet has said that she has “redirected aggression”. She is doing better with that BUT when I go to bed, Missy will often attack. Last night she came in to bed and I thought all was well, then she bit me on the hand. Can anyone give me any answers? If I sleep in my recliner then all is well. Once the initial bite is over, then she calms down and goes to sleep. Closing the bedroom door is not an option because that is the only place that I can put her cat pan (I live in a small apartment) Thank you for any help you can give.

    Never having had a tortie before, when I got Lola and she started to run round the house growling she sounded more like a dog than a cat. I have got used to it now but it still surprises me when it happens in the middle of the night.Purring can change to hissing in a split second and you need to move pretty quickly or else.I would not change her though but sometimes !!!!! typical tortie attitude.

      “Change in a split second” seems to be the tortie mantra 🙂 Your Lola sure sounds like she’s got tortitude and then some, Wendy!

    Torties are the Gemini’s of the cat world

    Time for a Gigi story 😉

    For those that don’t know her, Gigi is our senior “tortie with white”. We took her in when she was about 5 years old when her owner passed away. She is long haired and 18 pounds, looks like a stuffed toy.

    As much as Kasey was the Warrior Queen, Gigi is the most docile, domesticated cat I have ever seen.

    However, she does not like the attention from, and activity of, young animals, as our young Shih-Poo pup found out.

    Gigi was sitting in the sun room, looking like the Empress Of The House that she is. All was serine and dignified, as it should be. The pup ran up, got in her face and started barking at her.

    Faster than I could see, she came around with a front paw and hit the little dog on the nose so hard I heard the impact from 20 feet away. There was no more barking and Gigi was left alone. It was over before it got started, Kasey would not have left it there and pursuit and greater punishment would have followed.

    There has not been a repeat performance. You know you are the Empress Of The House, when you can stretch out and sprawl on your back on the kitchen floor and the normally energetic young pup goes out of their way to avoid you 😉

      Once a Tortie teaches a lesson. A follow up is usually not needed. Unless it’s an orange kitty/They need constant reminders.

        “Unless it’s an orange kitty/They need constant reminders”

        Yes, right on time this morning, Timmy came to Freyja for his butt kicking appointment.

        It followed the predictable format; he initiated it, she was like “I don’t really want to do this, but if you insist”.

        Freyja wend on the floor on her side, he kept trying to attack her, only to take a beating each time.

        He is a nice cat, and smart in many ways, but sometimes does not make good choices.

        Good thing its all in (rough) play. Luckily for him, she does not follow Kasey’s attitude, she did not understand the concept of a play fight 😉

    Tim, our 9 1/2 pound orange guy has been choosing to play fight with Freyja in the morning lately.

    Perhaps its the cooler air that is stirring him up.

    Freyja does not particularly like this and responds accordingly.

    Freyja is a 3 year old, long hair, dark tortie. I think she is part Maine Coon because she is 15 pounds, and not over weight for her size.

    She is actually quite quiet and docile, unlike my still missed Warrior Queen, Kasey. She is a strong , calculating and skilled “scrapper”, though.

    Tim initiates, she goes immediately on her side, I believe he see’s as a sign she is submissive and he is winning.

    Actually, she does this so she can bite and use all 4 legs/paws. He lunges at her, she grabs him, kick and bites. He retreats, then tries again, getting pummelled in the process.

    Once he has had enough, the retreats and Freyja is left in peace, in possession of the living room floor.

    Did he learn from this?

    No. 😉

    There’s a good chance of it being repeated tomorrow morning.

      Orange kitties are cute, cuddly and kinda slow. Freyja put him in his place and kinda gently for a Tortie. Kasey would not have been that kind.

        “Kasey would not have been that kind.”

        Quite right.

        Taz was our 23 pound orange guy, Kasey was 15 pounds; a fairly bit tortie.

        Every once in a while, for reasons only known to him, Taz would come up behind Kasey and sniff her.

        Words cannot do justice to the result, which was quick, and not pretty.

        I’d just say to him, “how’d that work for ya last time, big fella?”

        He never did seem to learn from the experience though but that’s a typical orange boy. He was a friendly, good natured cat, he just didn’t make good choices sometimes 😉
