Have you ever encountered a strikingly unusual blue cat and wondered which breed it might belong to? Though rare, it could very well be a Russian Blue. There are a few ways to identify this unique breed when you come across one.
Steps
Recognize the characteristics of a Russian Blue cat

Learn about the breed. The Russian Blue is a purebred cat. The exact origin of this breed remains uncertain, but it is believed to have originated from the Archangel Islands in northern Russia. The harsh winters in that region are likely why the Russian Blue developed its thick and plush fur to keep warm.
- This breed began to be introduced to other parts of the world in the latter half of the 19th century, reaching the United States in the early 20th century.

Notice the size of the cat. Russian Blue cats typically stand around 25 cm tall at the shoulder, with an average weight of 5.5 kg. However, their size can vary, depending on their lifestyle, eating habits, and activity levels.
- The average lifespan of a Russian Blue cat is between 10 to 15 years.

Recognize the cat's general appearance. Russian Blue cats make an impression with their long, slim, and graceful bodies. They have an elegant, long neck, but their thick, plush fur can make the neck appear shorter.
- Their bodies are lean, with a small bone structure and well-defined, slender muscles.

Observe the cat's eyes. Russian Blue cats are known for their distinctive green eyes. This characteristic starts to develop around 4 months of age, seen in the outer rim surrounding the pupil, which gives the eyes their color. Kittens are born with blue eyes, but their eye color changes gradually as they grow older.

Examine the cat's head shape. The Russian Blue has a triangular-shaped face, often likened to the head of a cobra, with seven distinct flat planes. This contrasts with typical cats, which usually have round skulls resembling the shape of an apple. This feature sets the Russian Blue apart from other breeds.

Check the cat's fur color, nose, and paws. The most notable and unique feature of the Russian Blue is its coat, which gives the breed its name. Their fur is often described as blue, though it appears silvery-gray, with a thick, dense, and soft double-layered coat.
- When closely examined, each hair strand has a light gray or silver hue at the tip.
- The Russian Blue’s nose is black, and its paws have a lavender tint.

Consider the cat's personality. Russian Blue cats tend to be shy around strangers but are very affectionate once they bond with their owner. They are gentle and cheerful, making them ideal for first-time cat owners. A unique trait of the Russian Blue is their love for fetch, a characteristic more commonly found in dogs and quite rare among cats.
- Russian Blues typically only meow softly, unlike other oriental breeds with sharper faces, like Siamese or Havanese cats, which are known for their loud and frequent meowing.
- They have excellent observational skills and enjoy watching what’s going on around them, though they don’t always join in. Like many cats, they appreciate a calm atmosphere and will often retreat to a quiet space when there’s noise, like a vacuum cleaner running.

Check the cat's breed records. A cat will not be recognized as purebred without proper documentation. You cannot claim that a beautiful blue cat is a Russian Blue without paperwork to prove it. Without a pedigree, the cat is considered a domestic short-haired cat, which is the official term for non-purebred cats.
- Of course, this doesn’t mean the cat isn’t worthy of a home, but without proof, it will not be acknowledged as a Russian Blue by breeders and registries.

Consider the cost. Authentic Russian Blue cats are quite rare and typically expensive. The average price for a Russian Blue at a reputable cattery is around 1,000 euros. In the U.S., a Russian Blue kitten usually costs between 400-600 USD. Most cats labeled as "Russian Blue" at animal shelters are actually domestic short-haired cats, as high-value cats like Russian Blues are rarely abandoned.
- Reputable breeders have strict standards and often refuse to sell Russian Blue cats to families who cannot commit to proper care.
- All quality Russian Blue cats are spayed or neutered when sold to prevent breeding and to protect the breed from non-professional breeders flooding the market and devaluing the breed.
Consider DNA testing for the cat.

Think about getting the cat tested for DNA. If you're unsure about your cat’s breed and it lacks official documentation, you can consider having a DNA test done. Every animal has a unique DNA that reflects its breed. DNA can be seen as a fingerprint that reveals its genetic origins. These tests use the same technology that law enforcement agencies use, and pet DNA testing services are now available.
- Tests identify genetic markers that reveal the cat’s parental breed. Reputable facilities will compare the results with databases from the National Animal Genome Research Institute to ensure the most accurate results possible.

Choose your testing facility carefully. Veterinary-run labs are generally reliable. These places often offer genetic testing for diagnosing health issues and hereditary conditions. Their pedigree tests usually meet high standards.
- You may also buy testing kits online, but make sure to research the seller thoroughly before purchasing. You’ll want to ensure you're not wasting money and that the results are accurate.

Collect the sample. The process of collecting a sample from a cat is relatively simple. The genetic test kit includes two swabs. Use one swab to scrape the inside of the cat’s cheek for 5 seconds, then hold it in the air for 15 seconds to dry. Place it back into the container. Use the second swab to scrape the other side of the cat's cheek.
- Do not collect the sample immediately after the cat has eaten or drunk. Make sure the cat hasn't eaten for at least 15 minutes before taking the sample.
- Send the sample to the lab. After the lab receives the sample, typically by mail, the average time to get the results is 4 to 5 days via email or post.
