The Different Origins of the Korat and Russian Blue Cats


1. Korat cats


The Korat cats might appear in some corners of the world, but little do people know that they originated from a tropical land in Asia, Thailand.

In fact, they are the oldest and most respected breed of cats in this country. Formerly known as Siam, they’re called “Si-Sawat” cats, meaning “color of the Sawat seed.”

This cat breed is highly prized for its beauty and intelligence and is a lasting symbol of good luck and prosperity.

2. Russian Blue cats


As their name might imply, the Russian Blue Cats originated in Russia. With a long history, the exact origin of this breed is unknown.

However, they’re believed to first appear in the port city of Arkhangelsk (in Northern Russia), where they were known as the Archangel Cat.

During their history, the Russian Blue are brought to different parts of the earth. They landed in England in the late 1800s and were exhibited at the Crystal Palace cat show. They also appeared in the US in the early 19th century and became popular after World War II.

1. Fur


Both the Korat and Russian Blue are short-haired, and you might easily spot the similar gray hue of their fur. However, there are some subtle differences in terms of their coat that make each of these breeds unique.

  • The Thai-originated ones have finer coats than those from Russia, which tend to lie closer to the body. Plus, their coats are quite consistent in color scale, with little or no variation all over their body.

You’ll be impressed by how they earn a sparkling appearance thanks to their gray coat with silver-tipped blue (also called “sea foam” in Thailand).

  • The cold weather in Russia might inspire the development of this cat breed’s thick and plush double coat, compared to the thinner one of the Korat.

Plus, though the Russian Blue is well-known for its gray fur, the color might vary in shade (from light to dark gray-blue), with a slightly lighter color on its underbelly.

2. Head shapes


The Korat has a heart-shaped face with high cheekbones and a wide muzzle. They also have a large forehead which accentuates their head shape, forming a second heart on their face.

Meanwhile, the Russian Blue’s faces are smooth wedge-shaped, with a straight profile and a narrow muzzle. Plus, they have a broad face across their eyes, which gives the impression of a more curious expression.

3. Eyes


While the eyes of the Korat and Russian Blue cats share some similarities, there are also notable differences in size, placement, and color.

  • The Korat has almond-shaped eyes, which are often wide open. They look oversized for their heart-shaped face.
  • Korat kittens have golden green eyes. As they mature, their eyes turn vividly green or amber, one of the defining features that help them earn the nickname of the “meanest face”.
  • The Russian Blue cat eyes are also rounded but set wider apart on their face. One fun fact about this cat breed’s eyes is that they change their color from yellow to emerald green when they mature.

4. Ears


The ears of a Korat cat are set relatively high on its head and are slightly tilted forward. They’re large and have rounded tips.

The Russian Blue’s ears are also set high but a little further apart. They’re also large but tend to be more pointed compared to the Korat.

5. Body


If you’re looking for a cat to sit on your lap and cuddle with you, these two breeds are an ideal choice.

  • With 6-10 pounds in weight and up to 13 inches in length, the Korat cat’s body is muscular and considered semi-cobby. Thus, they are heavier than they might look.

Additionally, these cats have broad chests, curved backs, and slightly unequal leg lengths (the back legs are a little bit longer than the front ones).

  • The Russian Blues appear to be chunkier because of their double coat. However, they still have muscular bodies with longer legs than the Korat cats.

The fact is that this cat breed easily gets obese. So if you want to maintain that firm body, give it a suitable diet.

Additionally, there’s a difference in the body size of the Russian Blue cat male vs female (male ones are often bigger). Notice this feature will help you identify them more precisely.

The Key Distinct in Their Temperaments


The Russian Blue vs Korat are both breeds of cats with unique personalities. They’re known for their intelligence and affectionate nature. Still, their varied temperaments are the crucial aspect that helps you decide whether it’s suitable for your family.

Highly energetic as they are, the Korats are the most affectionate cats who don’t like being alone and always demand your love and attention.

The Russian Blues are slightly clinging to an independent lifestyle since they’re fine staying alone for a while, which is ideal for any owner who works outside all day.

How Much Do They Cost?

To adopt a Korat cat, you’ll have to spend around $600 and $800. But if you need to save a little money, the Russian Blue is still a great option for a nice pet. A purebred one will cost you about $400 to $600.

Remember that the Russian Blue price and Korat cat price are not fixed. It might vary depending on their age, condition, and even where you adopt them.

Another notice is that if someone’s asking, “What is the long hair Russian Blue cat price?”, it’s not in the range between $400 and $600. The reason is that a long-hair Russian Blue is a Nebelung cat, a completely different cat breed with a higher price range.
