Reasons for cat dander allergy:
Cat hair itself doesn't cause allergies. What causes allergies in humans is a tiny protein called an allergen. This allergen is present in a cat's sebaceous glands and is released through sebum. It adheres to dry skin, forming dandruff. Allergens can also be found in a cat's saliva and urine, and can be released into the air when the cat licks its fur. These allergens, which trigger allergies in cats, attach to dandruff or shed fur and spread throughout the home. Therefore, items like curtains and bed sheets can accumulate a lot of cat dandruff and fur, and must be thoroughly cleaned. Avoiding carpets, using a vacuum cleaner frequently, and regularly washing curtains are all effective ways to reduce allergens in the home.
