Description
The majority cases of cat allergies are IgE-mediated allergic reactions. The main allergens in domestic animals (cats, dogs, guinea pigs, hamsters and other rodents, birds, rabbits, horses, sheep, goats, etc.) are the epidermis, saliva, fluff, feathers, secretions, etc. Getting on the fur of an animal, allergens, upon contact with an animal, or by air, or by contact with products that contain an allergen (clothes, pillows, blankets) enter the human body.
Cat epithelium allergens are usually attached to small dust particles that float in the air for a long time, and also settle on furniture, carpets, and draperies. The allergenic properties of wool, dander, saliva and urine of animals do not depend on their breed or length of wool.
Allergy symptoms are manifested in the form of coughing, sneezing, watery eyes, chest tightness, nasal congestion, rash, etc. Removing the animal from the house is not always enough for recovery - animal allergens are found inside the house for another 5-6 months. In some cases, people who are initially allergic to a cat become "immune" to their cats over time, but may continue to have allergic reactions of varying intensity to other cats.
