Winged cats have been known to exist since the 19th century. Some sightings of winged cats may be explained by matting due to poor grooming. When the cat runs, the dense mats flap up and down giving the impression of wings. However, usually cat wings are the result of a genetic skin disorder called cutaneous asthenia, which makes the skin across the shoulders and back extremely elastic. Cats that have this disorder can often even actively move their ‘wings’ because they contain muscle fibers! Unfortunately, these unique cats cannot flap them in a bird-like manner.
