Grey (referred to as blue in the cat fancy) is a common coat colour that consists of a slate grey coat. This stunning coat pattern is the result of the dilute gene which alters the deposit of pigment within the hair shaft. Blue can be found in both random-bred as well as purebred cats. The Nebelung, Russian Blue, Korat and Chartreux are well-known cat breeds that have blue coats.
