A "cat-eye" refers to a specific shape of the eye that resembles the eyes of a cat, characterized by a narrow, elongated pupil and a slightly slanted appearance. This eye shape is often associated with certain breeds of cats, such as Siamese or Persian cats, which have distinctively shaped eyes that enhance their expressive features. In the context of makeup, "cat-eye" is a popular eyeliner technique that creates a winged effect at the outer corners of the eyes. This style aims to elongate the appearance of the eyes, giving them a more dramatic and alluring look, reminiscent of the natural shape of a cat's eyes.
