If you own a Siamese cat and wonder if you have a purebred on hand, you can look for specific physical characteristics, such as a pointed coat with a face, tail, ears, and legs in a darker silver shade. Moreover, your Siamese cat should have blue eyes, a long, slender body, and a wedge-shaped head. By checking their pedigree, you can also determine if you have a purebred Siamese cat. Most reputable breeders provide the cat’s pedigree upon sale. If you haven’t received one, you can have a DNA test done to confirm their breed—just research companies that offer cat DNA tests and visit one. These tests can also reveal genetic health conditions.
