According to TICA’s official standard for the Napoleon, these breeds represent the only permissible outcrosses one may utilize to create the Napoleon. This includes the combinations Napoleon × Napoleon, Napoleon × Munchkin, and Napoleon × a member of the Persian breeds (including Persians, Himalayans and Exotic Shorthairs.
