There is a lot of debate over whether all Russian Blue cats have green eyes. Some people say that this is simply a myth, while others swear that it is true. So, what is the answer? Well, the truth lies in breed standards: vivid green eyes are a hallmark of the Russian Blue. While not all blue-colored cats have green eyes, and not all green-eyed cats are blue, purebred Russian Blues that meet the breed standard are blue-coated and have green eyes. Read on to learn more about eye color in Russian Blue cats and how it develops.

Russian Blue Cats & Eye Color
Most Russian Blue cats will have green eyes, but there might be a small percentage that are born with blue or amber eyes. The reason for this is that the gene that determines eye color in Russian Blues is not completely understood. However, what we do know is that the majority of Russian Blues have a mutation in their MCOP gene, which is responsible for eye color. This mutation is what causes the green eyes that are so characteristic of Russian Blues.
Russian Blue Cats & Eye Color at Birth
One thing to keep in mind is that Russian Blue kittens (and all kittens) are born with blueish eyes, and it can take several months for their true eye color to develop. So, if you are looking for a Russian Blue kitten, don’t be surprised if they have blue or yellow eyes. However, as they get older, their eyes will begin to change color, and eventually most will settle into the green hue that is so characteristic of Russian Blues.
Remember that not all Russian Blues will have green eyes. Some may have blue or amber eyes.

Why Are They Called Russian Blue Cats?
Russian Blue cats are believed to have originated in the Russian port city of Arkhangelsk, located on the White Sea, roughly 150 miles south of the Arctic Circle. This is why they are often known as the Archangel cats.
The breed takes its name from its distinctive bluish-gray coat. Russian Blues are thought to have been introduced to England in the late 1800s, likely brought by sailors returning from Russia. From there, the breed gradually gained popularity across Europe.

Frequently Asked Questions (FAQ)

Do Russian Blue Cats Make Good Pets?
Yes, Russian Blue cats make excellent pets. They are very affectionate and loving, and they bond well with their owners. They are also very intelligent and can be trained to do tricks.

Do Russian Blue Cats Get Along With Other Pets?
Russian Blue cats typically get along well with other pets. However, it is important to introduce them slowly and carefully to any new animals in the home. Russian Blues are also known for being very shy around strangers, so if you have a lot of visitors in your home, this may not be the best breed for you.

Are They Prone to Any Health Problems?
Russian Blue cats are generally a healthy breed. However, like all cats, they are susceptible to certain health problems, such as dental disease, kidney problems, and arthritis. It is important to take your Russian Blue to the vet regularly for checkups and vaccinations to help prevent these diseases.
How Much Exercise Do They Need?
Russian Blue cats are not a particularly active breed. They do enjoy playing, but they do not need a lot of exercise. A simple scratching post or cat tree will provide them with enough stimulation.
Do They Come in Any Other Colors?
No, Russian Blue cats only come in one color: bluish-gray. However, they can have different shades of gray, from light to dark. Russian Blue cats are also known for their green eyes, which is a result of a genetic mutation. However, there is a small percentage of Russian Blues that have blue or amber eyes.

Conclusion
As you can see, Russian Blue cats come in one coat color, blue, and one eye color, green, which are so associated with this breed. So, if you are looking for a Russian Blue, you can expect them to have green eyes. But do not be surprised if you find a Russian Blue kitten with blue or amber eyes, since their definitive eye color develops later in life. After all, they are still beautiful cats, no matter what color their eyes are!
