The Russian Blue cat, commonly known as the Russian Blue, is a pedigreed cat breed characterised by a solid blue coat that has been the breed’s defining feature for over a century. The Russian Blue breed is accepted for registry and holds championship status with all major international cat registries. It is a short-haired breed noted for its dense, plush double coat of pale blue-grey fur with a distinct silver sheen, and for its bright emerald green to yellow-green eyes.
