Formal recognition came in the early 20th century. World War II severely threatened the breed's survival, but dedicated breeding programs successfully restored its population. Today, the Chartreux remains a relatively rare treasure outside of France, celebrated as a national heritage breed.

Russian Blue Origins

The Russian Blue originated in the port city of Arkhangelsk, Russia, where sailors valued these silver-blue felines for their companionship and pest-control abilities. British sailors introduced them to England in the 1860s, where they quickly gained acclaim in cat shows. Like the Chartreux, World War II posed a severe threat to the breed. Its survival is credited to meticulous breeding programs that carefully preserved its core bloodlines.

Modern Russian Blues descend from these carefully maintained lineages, preserving the breed's iconic appearance and temperament. They enjoy worldwide recognition and steady popularity among cat aficionados.
