Dilute Tortie: Cat Guide & 6 Interesting Facts (With Pictures)

Dilute tortie cats are one of the most gorgeous and unique cats on the planet. They have a coat that contains two colors and diluted pigmentation. Despite their unique coat, these cats have just about the same health and nutritional requirements as cats with a plainer coat, making them both beautiful and low maintenance!

To find out more about the dilute tortoiseshell cat, keep reading. In this guide, we go into detail about what creates a dilute tortie coat and how to take care of one of these cats. At the end, we also include six interesting facts about dilute torties.

Let’s learn more about these purrfect cats!

Cat ball divider 1Dilute Tortoiseshell Cat

A dilute tortie, or dilute tortoiseshell, is a cat that comes with the popular double-colored diluted coat pattern. It is important to emphasize that “dilute tortie” does not refer to a breed of cat. Instead, it refers to a coat coloration that many breeds can have.

Standard torties have a coat that includes orange and black fur. Dilute torties, on the other hand, do not have orange and black colorations. On the contrary, their double-colored coat includes a muted color scheme, often looking blue and yellow.

Dilute Tortie Coat

You may be wondering how dilute torties get this unique coat scheme. The answer is rather simple to state but potentially difficult to understand. Genetics impact a cat’s coat. As a result, dilute torties have a specific genetic background, which allows them to have a unique diluted double-colored scheme.

To fully understand the dilute tortie coat, we have to dig into genetics. This is a bit confusing, but the effort is worth it.

Before jumping into coat genetics specifically, it’s important to understand that there are two sex chromosomes: a Y chromosome and an X chromosome. Females have two X chromosomes, whereas males have one X chromosome and one Y chromosome.

Tortie Coat Genes

Let’s talk about the genes behind the tortie, or double-colored, coat first. These genetic factors apply to standard torties, as well as dilute torties. We will talk about dilute torties specifically in the next section.

Even though the X chromosome is considered a sex chromosome, it contains much more information than just an animal’s biological sex. For example, it is also responsible for a cat’s coat color. Because females receive two X chromosomes, female cats can receive two separate coat instructions, whereas males can only receive one.

Whenever female cats receive a code for a black coat and a code for an orange coat, they end up having a tortoiseshell coloration, complete with both colors. Males, on the other hand, only receive one X chromosome, meaning that they only get instructions for one color.

Dilute Coat Genes

So far, we have only looked at the genetics behind the tortie coloration. More genetic factors are required for the dilute coat gene. The melanophilin gene, or the MLPH gene, is responsible for the coat’s pigment. In other words, this gene allows the cat to produce orange or black pigment. Sometimes, this gene is mutated through a recessive gene.

Whenever the gene mutates, the coat pigment doesn’t work as it should. As a result, the tortie coloration becomes diluted, turning the orange color yellowish and the black color bluish. Since this mutation occurs through a recessive gene, both parents must carry the trait in order for the offspring to be a dilute tortie.

To put the tortie genes and dilute genes together, dilute torties have two different color codes, one on each X chromosome, which allows the cat to have orange and black fur. In addition, they have the MLPH gene, which mutates the pigmentation of the coat colors. This turns the orange fur yellow and the black fur blue. As a result, they have a diluted tortie coat.

Luckily, the genes behind the dilute tortie coat affect nothing other than the coat coloration. In other words, your tortie should not have any special needs or health considerations due to the dilute tortie genetics. For this reason, you would take care of a dilute tortie just like you would any other cat.

Cat Health

Although there are certainly exceptions to this statement, dilute tortoiseshell cats tend to be very healthy and dependable cats. Since the cat breeds that can have this coat are healthy overall, dilute torties come with very few common health issues.

One of the more common issues that plague dilute torties is obesity, though this is an issue due to the cat’s feeding schedule and owner, not the cat’s health. To ensure that your dilute tortie remains healthy, make sure to provide it with proper nutrition and exercise.

Cat Nutrition

Most importantly, make sure to provide your dilute tortie with the proper nutrition. Something that a lot of people do not realize is that cats are obligate carnivores. This means that they need a diet that consists primarily of meat or animal organs. Never put your cat on a vegan or vegetarian diet.

Since obesity is a common issue in felines, it is important to feed your cat the right amount of food. The food amount will depend on your cat’s age, size, and weight. Talk to your veterinarian to find out exactly how much food you should be feeding your dilute tortie.

Generally speaking, veterinarians recommend feeding an adult indoor cat ¼ of an 8oz. cup of dry cat food a day. Additionally, feed the adult cat 2.5oz. of canned cat food once a day, which is about ½ up a can of regular cat food. You will need to adjust this food recommendation for younger or older cats, as well as cats with special health concerns.

Regardless of the cat’s age, weight, or health, one thing you should constantly provide is clean drinking water. Cats need a lot of water to survive, just like other mammals. Put the drinking water somewhere that they can easily find it. It’s also a good idea to slightly lift it off the ground to prevent debris or other contaminants from entering the water.

Once again, talk to your veterinarian to find a specific food recommendation and regimen based on your individual cat’s needs.

Cat Maintenance

In addition to feeding your dilute tortie the right nutrition, make sure to maintain its fur. Exact maintenance will depend on the cat breed. Nevertheless, you should maintain your cat’s fur by brushing it regularly and bathing them, as necessary.

Brushing your cat’s fur will keep it clean and free of mats. Not to mention, it will reduce allergens and pet dander in the air. If your dilute tortie has a long hair coat, make sure to brush their hair more often and be gentle while doing so.

As for bathing your cat, this is something you should not have to do is often, especially if you have a short-haired breed. Only bathe your cat if you notice a foul odor or attached dirt and debris. Older or overweight cats may need a bath more often since they may have trouble reaching all parts of their body.

Cat Personality

Many dilute tortoiseshell cat owners swear that their cats have an attitude, which they call a “tortitude.” They believe their tortie shows much more sass and personality than cats with a different coat. Interestingly, some studies have shown a potential link between coat color and aggression, though the studies are not conclusive.

It’s more important to pay attention to your cat’s individual personality than their coat color. In most cases, a cat’s background and living situation will determine its personality more than its appearance or coat.

Here are some more interesting facts about dilute torties:

1. Dilute Tortoiseshell Cats Are Almost Always Female…

Since coat color is determined by the X chromosome, dilute torties are almost always female. In order to have both colors, the cat must receive two separate sets of instructions regarding the cat’s coat coloration. As a result, healthy males only receive one X chromosome, making it impossible to have a tortie coat.

2. … But Males Can Inherit the Coat Too

However, it is not impossible for males to inherit a tortie coat. When this happens, a male cat receives two X chromosomes, in addition to the Y chromosome. This is a genetic anomaly that results in a male tortie cat with two colors. A male cat with two X chromosomes will have a number of other health issues because of this genetic anomaly. Most commonly, it will not be able to reproduce.

This genetic anomaly is known as Klinefelter syndrome. It can also be found in humans. Much like cats with Klinefelter syndrome, humans with a genetic anomaly will also be unlikely to reproduce. Because males with this gene cannot reproduce, it is impossible to breed dilute tortie cats, no matter how hard you try.

3. Many Breeds Can Have Dilute Tortie Coats

Many people mistake dilute torties as being a breed of cat. On the contrary, dilute tortie simply refers to a specific coat combination. A variety of cat breeds can have this beautiful coat. For example, the American Shorthair, Cornish Rex, and Maine Coons are some of the most popular cats that have dilute tortie coats.

The length of cat hair does not determine whether or not the breed can have this unique coat color either. Both short and long-haired cats are known to be dilute torties.

4. They May Have an Attitude

As we described above, many dilute tortie owners claim that their cat has an attitude outmatched by none. Though the environment definitely determines a cat’s personality more than its coat, studies are suggesting that there is a link between aggression and coat color.

Some experts estimate that this additional aggression is linked to female hormones. Since the more aggressive cats tend to be female, their aggression is probably due to hormones, not specifically the color of their coat.

5. They Have A Lot of Folklore Surrounding Them

Torties are known to be the star of many myths and folklore. For example, male torties are known as good luck whenever they enter the home in Ireland. Meanwhile, the coat color is associated with money and wealth in the US, which is why these cats are sometimes called “money cats.”

6. They Aren’t the Same As a Calico Cat

Sometimes, you may hear a cat referred to as a “tortoiseshell calico,” but this is impossible. Torties and calicos are two different types of cat coats. As we learned above, torties have two colors—black and orange. Calicos, in contrast, have three colors—white, black, and orange.

Like torties, calico coats are typically only found in females since the coat color is determined by the X chromosome. Male cats can have a calico coat as well, so long as they have Klinefelter syndrome.
