Feathers of pet cats, dogs and p…

In modern life, people have a close relationship with animals, not only cats, dogs and pets are everywhere, but also birds and poultry are in frequent contact. However, dander on these animals is also a common allergen and should be taken seriously by people with allergies.

Allergens are also known as allergens or sensitizing allergens. All substances that can cause allergic reactions in the human body are allergens. There are hundreds of common substances in life, most of which come from substances in the environment, so there are large regional differences. These substances do not overreact in a normal human body, but in allergic people they are air purifier for cat allergies as “foreign molecules” and cause allergic reactions.

First, allergens, as antigens, enter the human body through inhalation, ingestion, contact or injection, resulting in corresponding antibodies and sensitization. When exposed to the allergen again, an allergic reaction occurs and allergic symptoms appear. Generally speaking, the first exposure to the substance does not cause allergy, and repeated exposure will only cause allergic symptoms. Allergens can be detected clinically by skin tests or serological tests.

So, can pets like cats and dogs cause allergies? Most studies suggest that pets like cats and dogs can cause allergies. These pets have some allergenic proteins that we call “allergens”. For example, the dander, hair, and saliva of cats and dogs contain allergenic proteins. If there are many cats in the house, the concentration of indoor allergens will also increase. In addition, cat hair may attach mites, pollen, etc. , which is also a common allergen.

The main symptoms of animal dander allergy are: sneezing, nasal congestion, runny nose, facial pain due to nasal edema, coughing, chest tightness, shortness of breath, wheezing, watery eyes, redness, swelling, itching, rash, urticaria, etc.

If you want to know if your pet is allergic, go to the hospital for an allergen test. Serum-specific antibody (sIgE) testing or skin prick testing are good options. If an allergy to a social pet is confirmed, the best approach is to give the pet to another person to avoid re-contact with such a research pet.
