In the US, there was an attempt to establish the Silver Persian as a separate breed called the Sterling, but it was not accepted. Silver and Golden longhaired cats, recognized by CFA more specially as Chinchilla Silvers, Shaded Silvers, Chinchilla Goldens, or Shaded Goldens, are judged in the Persian category of cat shows. In South Africa, the attempt to separate the breed was more successful. The Southern Africa Cat Council (SACC) registers cats with five generations of pure bred Chinchilla as a Chinchilla Longhair. The Chinchilla Longhair has a slightly longer nose than the Persian, resulting in healthy breathing and less eye tearing. Its hair is translucent with only the tips carrying black pigment, a feature that gets lost when out-crossed to other coloured Persians. Out-crossing also may result in losing nose and lip liner, which is a fault in the Chinchilla Longhair breed standard. One of the distinctions of this breed is the blue-green or green eye colour only with kittens having blue or blue-purple eye colour.
