What allergy can a cat cause? - in detail
Cats can cause allergic reactions in humans primarily due to proteins found in their saliva, skin dander, and urine. The most common allergen is Fel d 1, a protein secreted by sebaceous glands in the cat’s skin and present in their saliva. When cats groom themselves, this protein is transferred to their fur, which then becomes airborne as the fur sheds. Inhalation of these airborne particles can trigger allergic reactions in sensitive individuals. Symptoms of cat allergies typically include sneezing, runny or stuffy nose, itchy or watery eyes, coughing, wheezing, and skin rashes. In severe cases, exposure to cat allergens can exacerbate asthma, leading to difficulty breathing, chest tightness, and even asthma attacks. Additionally, cat allergens can linger in the environment for extended periods, adhering to furniture, carpets, and clothing, making it challenging to avoid exposure. While some breeds are marketed as hypoallergenic due to producing less Fel d 1, no cat is entirely allergen-free. Managing cat allergies often involves minimizing contact with cats, using air purifiers, regularly cleaning the home, and consulting with a healthcare provider for medications or immunotherapy options.
