* Siamese coat patterns: Siamese cats are known for their distinct "point" coloration, meaning they have darker fur on their extremities (face, ears, paws, and tail) and a lighter body. This pattern is caused by a gene that affects how melanin (the pigment that gives fur color) is produced.
* Siamese eye color: Siamese cats almost always have blue eyes. This is also linked to the same gene responsible for their point coloration.
* Pure white coat: A pure white coat, without any points, is not a characteristic of Siamese cats. It would mean that the cat doesn't have the Siamese point gene.
So, if a cat is pure white with blue eyes, it cannot be a Siamese. It's likely a different breed, such as a:
* Snowshoe: A breed with white paws, a white chest, and blue eyes.
* White Persian: A long-haired, white cat with blue eyes.
* Domestic Shorthair or Longhair: White cats with blue eyes are common in these breeds.
If you're unsure about your cat's breed, it's always a good idea to consult with a veterinarian or a cat breeder for an expert opinion.
