Katteallergener

Katteallergener refer to specific proteins produced by cats that can trigger allergic reactions in sensitive individuals. The most common and potent allergen is Fel d 1, found in a cat's saliva, skin glands, and urine. When cats groom themselves, they spread saliva containing Fel d 1 over their fur and skin. This protein then becomes airborne, especially from shed dander (dead skin cells), and can remain in the environment for extended periods. Other less significant allergens include Fel d 4, found in saliva, and Fel d 7, present in dander.

Symptoms of a cat allergy can vary in severity and may include sneezing, runny nose, itchy or watery eyes, skin rashes or hives, and in more severe cases, difficulty breathing or asthma exacerbation. Allergic reactions occur when the immune system mistakenly identifies these cat proteins as harmful invaders, releasing histamine and other chemicals that cause inflammation and discomfort.

Individuals with cat allergies may react to direct contact with cats, as well as to allergens present on surfaces like furniture, clothing, and even in the air. The concentration of allergens can be higher in homes with multiple cats or where cats spend most of their time. While all cats produce allergens, some breeds may produce lower levels of Fel d 1, though no cat is truly hypoallergenic. Management strategies often involve reducing exposure through cleaning, air filtration, and sometimes medication or immunotherapy for severe allergies.
