The sparseness of hair on this breed is not the same as that which takes place on the Sphynx cat. In the case of the Lykoi some of the hair follicles lack all of the necessary anatomy which is required to create hair. This causes the lack of undercoat. This cat becomes temporarily bald during the moulting season. Sometimes individual cats remain completely hairless after six months. Sarah Hartwell says that this may be indicative of “unwanted genes”.
