Why is there an allergy to a hairless cat? - briefly
Allergies to hairless cats are caused by proteins found in their saliva, skin secretions, and dander, not their fur. These allergens can still trigger reactions in sensitive individuals despite the absence of hair.
Why is there an allergy to a hairless cat? - in detail
Allergic reactions to hairless cats, such as the Sphynx breed, are often misunderstood due to the common misconception that allergies are solely triggered by fur. In reality, the primary allergen responsible for cat allergies is a protein called Fel d 1, which is produced in the cat’s saliva, skin glands, and urine. When a cat grooms itself, this protein is deposited on its skin and, in the case of furry cats, on its fur. Hairless cats, despite lacking fur, still produce Fel d 1. Their skin is exposed and can shed dander (dead skin cells) that carries the allergen into the environment. Additionally, hairless cats may produce more skin oils to compensate for the lack of fur, which can further distribute the allergen. The protein can become airborne and settle on surfaces, leading to allergic reactions when inhaled or when it comes into contact with the eyes or skin. People with cat allergies may experience symptoms such as sneezing, itching, watery eyes, or respiratory issues when exposed to hairless cats, just as they would with furry cats. The severity of the reaction varies depending on individual sensitivity and the level of allergen exposure. Regular bathing of hairless cats can reduce the amount of allergen on their skin, but it does not eliminate the problem entirely, as Fel d 1 is continuously produced. Therefore, the absence of fur does not equate to hypoallergenic qualities, and individuals with cat allergies should exercise caution when considering a hairless cat as a pet.
