Title: Russian Blue
Passage: Russian Blues are plush short-haired, shimmering pale blue-gray cats with emerald green eyes. Guard hairs are distinctly silver-tipped giving the cat a silvery sheen or lustrous appearance.

They are being used in Italy as a way to make Oriental Shorthairs healthier and more robust called RUS4OSH in FIFe.
