Purebred cats are specific breeds that have been selectively bred for certain traits, such as appearance, temperament, and health. Each breed has a distinct set of characteristics, including coat color, size, and personality. Examples of popular purebred cat breeds include Siamese, Persian, and Maine Coon. These cats are often registered with organizations like the Cat Fanciers' Association or the International Cat Association, which maintain breed standards. Purebred cats can be more predictable in behavior and appearance, but they may also be prone to certain genetic health issues associated with their breed.
