Skin & Coat
While sphynx cats lack a coat to shed or groom, they are not maintenance-free. Body oils, which would normally be absorbed by the hair, tend to build up on the skin. As a result, regular cleaning (usually in the form of bathing) is necessary; one bath a week is usually sufficient.
Care should be taken to limit the Sphynx cat's exposure to outdoor sunlight at length, as they can develop a sunburn, similar to that of human exposure. In general, Sphynx cats should never be allowed outdoors unattended, as they have limited means to conserve body heat in colder temperatures. Their curious nature can take them into dangerous places or situations.
Although Sphynx cats are sometimes thought to be hypoallergenic due to their lack of coat, this is not always the case. Allergies to cats are triggered by a protein called Fel d1, not cat hair itself. Fel d1 is a tiny and sticky protein primarily found in cat saliva and sebaceous glands. Those with cat allergies may react worse to direct contact with Sphynx cats than other breeds. However, conflicting reports of some people successfully tolerating Sphynx cats also exist.
