ロシアンブルー
The Russian Blue has bright green eyes, pinkish lavender or mauve paws, two layers of short thick fur, and a blue-grey-black coat. The color is a bluish-gray that is the dilute expression of the black gene. However, as dilute genes are recessive ("d") and each parent will have a set of two recessive genes ("dd") two non-Color-Point Carrier (non-CPC) Russian Blues will always produce a blue cat. Due to the breeding with Siamese after World War II, there are color-point genes floating around. If two carriers are bred together, then they will produce a litter of mixed colors—solid blue or white with blue-point like a Siamese. People call these CPC cats "color-point", "whites" or "pointed" Russians. In most registries, one cannot register, breed or show a color-point Russian. These color-point (blue-point) cats are called Color-Point-Russian Blue (Blue Point Russian Blue) or more informally as Pika Blu (or pika blue) cats and have the same general characteristics as the Russian Blue cats.
