Russian Blue Siamese Mix Kittens


You should be able to find a Russian Blue Siamese kitten for a reasonable price. It may actually be harder to find a mixed breed kitten than a purebred, as it’s less likely that breeders will specialize in this mix.

It still makes sense to take the time to find a reputable breeder with experience and references. Buying a kitten from an accidental litter could result in kittens from parents who haven’t had the relevant health checks. Make sure any breeder is happy to let you visit the parent cats and the kittens, as well as provide references and evidence of health checks. It’s also worth speaking to local rescue centers to see if they have any kittens available that need loving homes.

3 Little-Known Facts About the Russian Blue Siamese Mix

1. They Can Be Many Different Colors

Your Russian Blue x Siamese kitten may have the classic blue coat of their Russian Blue parent, or they may end up with the Himalayan color-pointed coat of their Siamese parent. Color-pointed kittens are born white, so you’ll have to wait until they’re a few weeks old until you know what color their points will be.

2. With a Mixed-Breed Kitten, You’ll Never Know What You’re Going to Get

The temperament, appearance, and personality of a purebred kitten are usually easy to predict because the parents will have similar characteristics. With a mixed-breed kitten, the possibilities are broader. Each kitten can end up being like one of the parent breeds or a blend of both! The only way to know what your kitten is going to be like is to wait and see.

3. The Russian Blue Is a Natural Breed

The Russian Blue is a natural breed because they occurred without any help or selective breeding from humans. They weren’t seen outside their native Russia until 1875 when they were exhibited at the first-ever cat show held at Crystal Palace in 1875. Since then, they’ve been well-loved the world over, thanks to their affectionate yet reserved temperament.

Temperament & Intelligence of the Russian Blue Siamese Mix

The temperament and intelligence of mixed breeds are always harder to predict than those of purebred cats because there’s a wider range of characteristics for them to inherit. The best thing to do is make sure you like the personality of both parent breeds, as your kitten could end up more like one than the other.

Are These Cats Good for Families? 👪

This cat is a great choice for families, as they are likely to be both affectionate and playful. Russian Blues can be a little timid around strangers or loud noises, so it may take them time to become accustomed to children and visitors. Siamese cats are usually far more bold and confident, so if your kitten has more of a Siamese personality, they’ll usually love playing with kids all day long!

Does This Breed Get Along With Other Pets?

Both the Russian Blue and the Siamese tend to get along well with other pets, especially if they’re introduced to them while they’re kittens. Russian Blues can be quite reserved, so you may need to keep introductions slow and go at your cat’s pace. Siamese can be far more outgoing and confident, so if your kitten has more of a Siamese personality, then the introductions may take less time.

Neither breed has an overly high prey drive, but you’ll still want to take care not to leave them unattended around smaller pets, like guinea pigs or mice.

Things to Know When Owning a Russian Blue Siamese Mix

Any cat breed has specific requirements that their new owner needs to be sure they can meet. Mixed breeds can have a wide range of possibilities when it comes to the amount of food, exercise, or training that they need.

Food & Diet Requirements 🐡

Your mixed-breed kitten will need a high-protein cat food formulated specifically to meet the requirements of growing kittens for at least the first year of their life. Look for a food with real meat as the first ingredient, and follow the feeding guidelines for that specific brand. Russian Blues can be prone to obesity, so keep a careful eye on your kitten’s weight and ask your vet to assess their body condition if you’re concerned. Siamese cats, on the other hand, are almost always svelte and easily maintain a healthy weight, so adjust your kitten’s rations depending on which body type that your kitten seems to have inherited.

Exercise 🐈

The amount of exercise that your mixed kitten needs will depend on what kind of temperament that they inherit. Siamese cats are generally high-energy, while Russian Blues are more laid-back. Even if your kitten does end up being chilled out, they still need physical activity, so encourage them to play with interactive toys, and make sure there are plenty of opportunities for them to play on scratching posts, perches, and even an outdoor cat enclosure.

Training 🧶

Both the Russian Blue and the Siamese are clever cats that love the challenge of mental stimulation. They will love training sessions, and using positive reinforcement or clicker training is a great way to bond with your cat and teach them cool new tricks. You can even teach your cat to walk on a harness and leash and take them out to explore the backyard.

Grooming ✂️

Your kitten may inherit the thick and dense coat of the Russian Blue or the thinner coat of the Siamese. Either way, they should only need brushing once a week or so for most of the year. Most short-haired cats shed twice a year, usually coinciding with the seasons changing. At this point, you may want to brush your cat once per day to remove all the dead hair.

It’s also a good idea to check your cat’s nails and ears once a week, and trim or clean them as needed. One of the most common health problems in domestic cats is dental disease, so try to brush your cat’s teeth at least once a week, if not more.

Health and Conditions 🏥

Both the Russian Blue and the Siamese can suffer from a range of different health conditions, although the Siamese generally has a longer list of potential health issues than the Russian Blue. Whether your kitten inherits any of these will be down to their genetics, so there’s no way to predict which may affect your kitten.

As a general rule, the good news is that mixed-breed cats are often healthier than purebred cats. It’s always best to ask for the vet to give your kitten a full health check every year, to help catch any health conditions as soon as possible. We listed the most common health conditions that affect both the Russian Blue and the Siamese here.

Minor Conditions
  • Megaesophagus
  • Feline hyperesthesia syndrome
  • Convergent strabismus
  • Nystagmus
  • Feline asthma
  • Urinary tract complaints
  • Bladder stones
  • Obesity
Serious Conditions
  • Progressive retinal atrophy
  • Amyloidosis
  • Thymoma
  • Lymphoma
  • Mast cell tumors
  • Hip dysplasia

Male vs. Female

While male cats are usually a little larger and more affectionate than females, it’s hard to predict exactly what your kitten’s personality will be like when they grow up. It’s always best to choose your new kitten based on their character when you meet them, rather than choosing one simply because they’re male or female.

If you’re concerned about hormonal behaviors, like males urine spraying or females yowling when in heat, rest assured that almost all these behaviors will be reduced or eliminated when your kitten is neutered or spayed at the appropriate age.

Final Thoughts

Russian Blue and Siamese cats may have a different personality than their parents, and you’ll never quite know how yours will turn out. Russian Blues can be quiet and reserved, while Siamese are the complete opposite!

One thing that’s guaranteed is that your kitten will be affectionate, adorable, and a beloved member of your family from the moment that you pick them up and take them home.
