What is "japanese bobtail"

The Japanese Bobtail is a breed of domestic cat with an unusual "bobbed" tail more closely resembling the tail of a rabbit than that of other cats. The variety is native to Japan and Southeast Asia, though it is now found throughout the world. The breed has been known in Japan for centuries, and it frequently appears in traditional folklore and art.

As in most other breeds, Japanese Bobtails may have almost any color (or colors, arranged in any number of patterns). Predominantly-white are especially favored by the Japanese and by cat fanciers, and strongly represented in folklore, though other colorations are also accepted by breed standards.
