Russian Blue Siamese Mix: Pictures, Care, Traits & Info

The Russian Blue Siamese mix is a rare hybrid breed resulting from pairing a Russian Blue with a Siamese. These gorgeous cats are intelligent, affectionate, and loyal to their family members, but their appearance and remaining personality traits will depend entirely on which parent breed they favor. Read on to learn more about this interesting mixed breed to see if it’s right for you, your lifestyle, and your family.

Breed Overview


8–11 inches


6–15 pounds


12–15 years


Bluish gray, silver, slate, seal point, chocolate point, blue point, lilac point

Suitable for:

Families searching for a loving and intelligent cat


Affectionate, sensitive, intelligent, reserved, devoted, active

The Russian Blue Siamese mix is an interesting hybrid resulting from two very different breeds. While they do have some similarities, the parent breeds are very different in many ways. One thing is for sure: you’re going to receive a gorgeous cat, as both Russian Blues and Siamese cats are downright stunning.

However, their temperament will be a mixed bag. One kitten from the litter may be outgoing, extroverted, and vocal like their Siamese parent, while the next will be reserved, quiet, and shy like their Russian Blue parent.

Russian Blue Siamese Mix Characteristics

Russian Blue Siamese Mix Characteristics

A high-energy cat needs a lot of physical and mental stimulation to keep healthy and happy, while a low-energy cat needs minimal physical activity, but still needs mental stimulation. When choosing a cat, It’s important to ensure their energy levels match your lifestyle.
Cats that are easy-to-train are more willing and skilled at quickly learning prompts and actions with minimal training. Harder-to-train cats are usually more stubborn or aloof and require a bit more patience and practice.
Certain cat breeds are more prone to various genetic health problems, and some more than others. This doesn’t mean that every cat in those breeds will have these issues, but they do have an increased risk, so it’s important to understand and prepare for any additional needs they may require.
Due to their size or potential genetic health issues of a specific breed, some cats have shorter lifespans than others. Proper nutrition, exercise, mental stimulation, and hygiene also play an important role in your cat’s lifespan and quality of life.
Some cat breeds are more social than others, both towards humans and other cats and animals. Cats that are more social have a tendency to rub up on strangers for scratches or jump on laps for cuddles, while cats that are less social shy away, hide, are more cautious, and even potentially aggressive. No matter the breed or gender, it’s important to socialize your cat and expose them to many different situations.

Russian Blue Siamese Mix Kittens

While finding a breeder specializing in Siamese cats is relatively simple, the same cannot be said about Russian Blues. This is a relatively rare breed in North America, and folks with their hearts set on adopting one may need to wait quite some time before a kitten becomes available. That said, locating a breeder that specializes in mixing the two breeds will be even more challenging.

It is crucial, however, to do your due diligence if you do find a breeder focusing on the Russian Blue Siamese mix. We wouldn’t recommend adopting a kitten resulting from an accident litter, as proper genetic testing will not be done beforehand to ensure the health of the kittens.

Russian Blue Siamese Mix Origin & History

There is no origin story for the Russian Blue Siamese mix, though the history of the parent breeds is a lot easier to trace.

Russian Blues originated in the port of Arkhangelsk in Northern Russia, which is why they’re sometimes known as Archangel Blues. Sailors may have taken them from the Archangel Isles in Russia to Great Britain during the 1860s.

Siamese cats originated in Siam (modern-day Thailand). Legend says they were used to guard Buddhist temples and were therefore considered very sacred. Like the Russian Blue, the Siamese was transported to Great Britain in the late 1800s.

Temperament & Intelligence of the Russian Blue Siamese Mix 🧠

The Russian Blue Siamese mix may be a bit of a mixed bag when it comes to their personality, as it can depend on which parent breed they take after. The parents are precisely opposite in personality in many ways, so it’s impossible to know what to expect temperament-wise.

Russian Blues are known to be pretty reserved, especially around new people. They’re not particularly clingy or needy but are very sweet and gentle with their family members.

Siamese cats, however, are incredibly playful, social, and curious. They’re known for getting into mischief if they’re not given the enrichment they need to stay physically and mentally stimulated. They bond very closely with their humans and always want to be a part of the goings-on in the home.

Whereas a Russian Blue is content being on their own all day, a Siamese will be somewhat shadow-like toward their owner. Russian Blues are definitely introverts in the feline world, while the Siamese are, without a doubt, extroverts.

Are These Cats Good for Families? 👪

These cats can make fantastic family pets, especially if they take after their Siamese parent. Siamese cats are very gentle, playful, and friendly, making them terrific companions in homes with children. That’s not to say that Russian Blues wouldn’t make a good family pet, though. This breed is charming and can get along well with kids, though they’re not lap cats by default.

Both parent breeds tend to form a deep connection with one particular human family member.

Does This Breed Get Along With Other Pets?

The amiable and outgoing temperament of the Siamese DNA in this mixed breed’s blood makes them very compatible with other feline companions. But don’t be put off if your kitty takes after the other parent more. Russian Blues can also get along well with other cats, though they may need more time to learn to become familiar and friendly with a new face.

This mixed breed can also get along with well-socialized and trained dogs, provided they’re introduced properly.divider 1 paws

Things to Know When Owning a Russian Blue Siamese Mix:

Food & Diet Requirements 🐡

The best thing to feed a Russian Blue Siamese mix is a high-quality commercial diet approved by the Association of American Feed Control Officials (AAFCO) for their life stage (kitten, adult, or senior). Most vets also recommend feeding your pet a combination of wet and dry food to ensure your pet reaps the benefits of both types.

Free-feeding this breed is not recommended, as Russian Blues are prone to obesity. Try using a food puzzle or lick mat to banish boredom at mealtime and to slow down their eating speed.

Exercise 🐈

The Russian Blue Siamese cat can be a highly spirited and energetic kitty. They’ll need to be engaged in physical and mental stimulation regularly to stay happy, healthy, and out of trouble. Owners must provide opportunities for their agile cat to climb and perch. Offer plenty of cat trees, scratchers, toys, and window perches to encourage natural behaviors.

Training 🧶

This is a sensitive and gentle breed that responds best to positive reinforcement. They’re brilliant, so engaging them in activities and training is a great way to keep them stimulated and out of trouble. Some may be perfect candidates for harness and leash training, as well as other types of training, including tricks. However, please note that your cat may have a mind of their own, so it’s important to temper your expectations. The Russian Blue DNA in this breed’s blood can make them highly independent and even stubborn at times.

Grooming ✂️

This is a relatively easy breed in terms of grooming. They don’t have any requirements for routine washing, brushing, or combing, especially if they take after their Russian Blue parent in appearance. In fact, much fussing over their fur can actually ruin their double cat.

If they have the short, color-pointed coat of their Siamese parent, you should brush them once a week.

This breed has no specific eye, ear, or skin care requirements, either. However, if you notice them overgrooming or itching themselves, it’s best to check with a veterinarian to rule out any potential health conditions.

Health and Conditions 🏥

Both Russian Blues and Siamese cats have relatively long average lifespans of around 15 years. However, some Siamese cats have lived well into their 20s. While the mixed kitten resulting from these breeds may be healthier than their purebred parents, they still can be prone to the conditions often seen in their lineage.

Siamese cats are prone to pica (eating non-food items), asthma, amyloidosis, hypertrophic cardiomyopathy, mammary tumors, and hip dysplasia.

Russian Blues can be prone to obesity, diabetes mellitus, urinary tract diseases, and polycystic kidney disease.

As with all breeds, this mixed breed kitty can also develop dental issues and eye problems.

Minor Conditions
  • Dental issues
  • Eye problems
Serious Conditions
  • Mammary tumors
  • Hip dysplasia
  • Hypertrophic cardiomyopathy
  • Kidney disease
  • Urinary tract diseases
  • Asthma
  • Diabetes mellitus
  • Amyloidosis

Male vs Female

The only significant difference between male and female Russian Blue Siamese mixes is their sizes. Males are typically a little heavier and larger than their female counterparts.

Personality is not dependent upon sex, though it may play a small role in some cases. Unneutered male cats can develop aggressive behaviors, typically toward other intact males. They may also be more likely to spray inside the home than males who have been neutered.

1. This mixed breed may be suitable for some folks with allergies.

While there is no 100% hypoallergenic cat breed, folks with allergies may find living alongside a Russian Blue Siamese mix a little more tolerable than other breeds. The best part is that it doesn’t matter which parent your kitty takes after more, as Siamese cats have short coats that aren’t prone to heavy shedding, and Russian Blues are also relatively light shedders.

2. Siamese cats and Russian Blues are considered natural breeds.

A natural breed occurs through natural rather than artificial selection. Siamese cats are natural as their coat pattern was the result of a genetic mutation. Russian Blues are a natural breed as they came to be without any help or selective breeding from humans.

3. Every Russian Blue Siamese mix will look different.

There are many visual differences between a Russian Blue and a Siamese cat, so it’s impossible to know for sure what the kittens will look like. They may have a coat that’s a dark slate gray or shimmery silver like their Russian Blue parent or a pointed pattern (pale body with darker extremities) as seen in their Siamese parent.divider 1 paws

Final Thoughts

The Russian Blue Siamese mix is a rather unpredictable hybrid cat breed, both in appearance and temperament. Kittens resulting from such pairings can be extroverted, playful, affectionate, and social like their Siamese parent, or they could be sensitive, intuitive, and reserved like their Russian Blue side. Regardless of which side they take after more, this kitty is certain to bond tightly with their family members, though they may prefer one human over the others in the household.

These kitties will need a fair amount of enrichment, both mentally and physically, to stay happy and healthy. They’re quite active and limber, so the more opportunities you have for climbing and perching, the better.

The Russian Blue Siamese mix will be an affectionate and intelligent companion with a lot of love to offer their human, feline, and even canine housemates.
