This is a breed with an extremely long history. Thai royalty kept Siamese for generations. In fact, they loved their cats so much that they had everything planned for them once they were gone. When members of royal families passed away, their cat would take up residence in the temple where royalties remains were interred in. They would live there in luxury and comfort among monks.
This is Why ALL Siamese Cats Have Blue Eyes
Siamese cats have a type of albinism. This can be a little difficult to wrap your head around, as they obviously do not look like traditional albino animals. The genes responsible for the blue eye color, however, represent temperature-sensitive albinism.
