The Peterbald Russian cat breed resmebles the Oriental Shorthair which is closely related to which blue-eyed cat?
Oriental Shorthair The Oriental Shorthair is a breed of domestic cat that is closely related to the Siamese. It maintains the modern Siamese head and body type but appears in a wide range of coat colors and patterns. Like the Siamese, Orientals have almond-shaped eyes, a triangular head shape, large ears, and an elongated, slender, and muscular body. Their personalities are also very similar. Orientals are social, intelligent, and many are rather vocal. They often remain playful into adulthood, with many enjoying playing fetch. Despite their slender appearance, they are athletic and can leap into high places. They prefer to live in pairs or groups and also seek human interaction. Unlike the breed's blue-eyed forebear, Orientals are usually green-eyed. The Oriental Longhair differs only with respect to coat length.
Siberian blue robin The Siberian blue robin ("Larvivora cyane") is a small passerine bird that was formerly classified as a member of the thrush family, "Turdidae", but is now more generally considered to belong to the Old World flycatcher family, "Muscicapidae". It and similar small European species are often called chats. Recent research suggests that this species and some other East Asian members of "Luscinia" should be classified in a new genus, together with the Japanese and Ryūkyū robins. The genus name "Larvivora" comes from the new Latin "larva" meaning caterpillar and "-vorus" meaning eating ("vorace" to devour), and "cyane" is Latin for "dark-blue".
