ittens are energetic and require adequate playmates or toys as they can become mischievous if bored.  They have exceptional athleticism and rival even Abyssinians for their ability to leap and climb. Slow to mature, Russian Blues retain many of their adolescent traits both good and otherwise until they are 3–4 years old and even much older Blues can be easily enticed into play by their owners. Russian Blues are also highly intelligent. They have an excellent memory and will learn the hiding place of favorite toys (e.g., laser pointers) and lead their owners to them when they want a game. They also have a keen ability to remember favorite visitors and will race to greet familiar faces even if quite some time has passed between visits—a radical departure from their normally very reserved behavior around unfamiliar people.

Growth and maturity 

Russian Blues have a life expectancy of around 10–20 years, but some have lived up to a maximum of 25 years. They usually have few health issues as they tend to have little to no genetic problems and are not prone to illness. They are small to moderate-sized cats with an average weight of  when fully grown.  Males will typically be larger than females. Their gestation period is approximately 64 days.

Allergies 

Anecdotal evidence suggests that the Russian Blue may be better tolerated by individuals with mild to moderate allergies. There is speculation that the Russian Blue produces less glycoprotein Fel d 1, one source of cat allergies. The thicker coat may also trap more of the allergens closer to the cat's skin. Glycoprotein is one source of cat allergies, but this does not mean they are suitable to be homed with people allergic to cats as they will still cause the allergy to be affected, only to a lesser degree for short periods of time.
