Cats with curled ears, like the American Curl, Highland Fold, and Ukrainian Levkoy, possess a captivating appearance marked by their distinct ear shape. These breeds possess genetic traits that lead to curled or folded ears, contributing to their unique charm. While some breeds inherit this trait as a dominant gene, others experience it as a result of osteochondrodysplasia, a genetic condition influencing cartilage development. Although health concerns, such as osteoarthritis, joint issues, and heart disease, can arise, responsible breeding practices and proper care are crucial for their well-being.
