The Cymric a breed of domestic cat. Some cat registries consider the Cymric simply a semi–long–haired variety of the Manx breed, rather than a separate breed. Except for the length of fur, in all other respects the two varieties are the same and kittens of either sort may appear in the same litter. The name comes from Cymru, the indigenous Welsh name of Wales, though the breed is not associated with Wales, and the name was possibly given as an attempt to provide a "Celtic"–sounding name for the breed. The breed's Manx bloodline originated in the Isle of Man, though Canada claims to have developed the long–haired variant. The breed is called the Long–haired Manx or Longhair Manx by some registries, and has also been called the Manx Longhair.
According to Isle of Man records,[weasel words] the taillessness trait of the Manx (and ultimately the Cymric) began as a mutation among the island's domestic cat population. Given the island's closed environment and small gene pool, the dominant gene that decided the cats' taillessness was easily passed from one generation to the next, along with the gene for long hair. Long–haired kittens had been born to Manx cats on the Isle of Man, but had always been discarded by breeders as "mutants". Then, in the 1960s, similar kittens were born in Canada and were intentionally bred. This was the start of the increase of Cymric popularity. It took many years for the Cymric to be recognized as a breed of its own by cat associations. The Manx was recognized in the 1920s, but the Cymric was not shown until the 1960s and did not begin to gain popularity until the mid–1970s.
Cymrics are intelligent, fun–loving cats, and they get along well with other pets, including dogs. Cymrics are very loyal to their humans and enjoy spending quality time with them. As cats go, they can be easily taught tricks. Despite their playful temperament, they are gentle and nonaggressive. However, Cymrics are usually not overly demanding of attention. Cymrics are very playful and are exceptional jumpers. Like Manx, Cymrics are fascinated by water.
