First, read the English article below.

Keep in mind that Siamese from shelters may not be pedigreed, even if they look like Siamese cats. The only way to know for sure if a cat is Siamese is to read the cat's registration papers, which most shelter cats don't have. However, a cat from a shelter can make a wonderful companion. Rescue groups may have papers for their Siamese cats, depending on how the cats were obtained. If you want to be sure that you are getting a Siamese cat, do not get a Siamese cat from a backyard breeder or a pet store. Do your research first. Responsible breeders will be glad to give you references and tell you which cat associations they belong to. They will also provide registration papers and a health guarantee. Cat shows are excellent places to meet responsible breeders. If you do not know any breeders in your area and you cannot find a Siamese in a shelter, consider asking your local veterinarian for recommendations on how to find a Siamese cat. Your veterinarian may be able to refer you to a reputable breeder or Siamese rescue group in your area.
