Korkokatteihin

Korkokatteihin refers to a specific type of feline adaptation observed in some domestic cat breeds. This phenomenon involves a distinct physical characteristic where the ears exhibit a pronounced upward curl or hook at the tip. While not a universally present trait, it is most commonly associated with the American Curl breed, where it is a defining and intentional feature.

The unique ear shape is a result of a natural genetic mutation. This mutation affects the cartilage structure of the ear, causing it to bend backward. The degree of curl can vary, ranging from a slight gentle curve to a more pronounced, sickle-like shape. This variation is often described as a key characteristic that breeders look for and appreciate.

Beyond its aesthetic appeal, the corkokatteihin trait does not typically impact the cat's hearing ability. The internal ear structure remains functional, allowing for normal auditory perception. Cats with this ear type generally lead healthy and normal lives.

The genetic basis of the trait is autosomal dominant, meaning that if a cat inherits just one copy of the gene responsible for the curled ears, it will express the trait. This makes it relatively straightforward to breed for and maintain in specific cat populations. While the American Curl is the most recognized breed showcasing this trait, occasional instances of similar ear formations have been observed in other breeds or mixed-breed cats due to spontaneous mutation.
