Not much is known about this rare breed; however, it is believed that the Russian blue originates from northern Russia, specifically the Archangel Isles. According to the Cat Fanciers' Association (CFA), cat rumor has it that "the Russian blue breed descended from the cats kept by the Russian Czars. Assuming the Russian blue did migrate from northern Russia, it was likely via ship to England and northern Europe in the mid-1860s." As early as the sixteenth century, recorded history shows that trade ships passed between this territory and the British Isles, and the Vikings were active in both regions centuries prior, but there is no mention of the Russian blue cat until the nineteenth century.
This is simply not true. The bad comments I have seen have only been from owner who should have not owned a cat to begin with. People who don’t have problems don’t go posting on the internet about how they don’t have issues. Just like a golden retriever or any other more athletic intelligent breed some people simple don’t match with the breed. People who buy an athletic type animal yet wont met its requirement for attention and mental stimulation.
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
