What is a cat allergy?
A cat allergy is a hypersensitive reaction of the immune system to certain proteins produced by cats. These proteins, also known as allergens, are found in cats’ saliva, dander and urine. When a person with cat allergy comes into contact with these allergens, the body can trigger an allergic reaction.
How does a cat allergy occur?
In cat allergy, the immune system reacts to allergens as a threat, even though they are in fact harmless. This leads to the production of antibodies that release histamine and other chemicals. These substances cause the typical allergic symptoms such as sneezing, itchy eyes and breathing problems.
The main cause of cat allergy is the protein Fel d 1, which is produced in cats’ sebaceous glands and saliva. When cats lick themselves, they spread this protein over their fur, where it then spreads into the environment via dander and hair.
Can you get cat allergy without direct contact with cats?
Yes, it is possible to get allergic symptoms without direct contact with a cat. Cat allergens are light and remain suspended in the air for a long time. They can also attach themselves to clothes, furniture and carpets. As a result, people can get allergic reactions in a room where a cat has been before, even if the cat itself is not present.
Can people develop cat allergy later in life?
A cat allergy can develop at any age. Some people do not have an allergic reaction to cats as children, but develop it later. This may be due to repeated exposure to cat allergens, making the immune system more sensitive.
What is the difference between a cat allergy and another allergy?
A cat allergy is specifically caused by the proteins in cat dander, saliva and urine. This differs from other common allergies such as:
- Hay fever: caused by pollen from trees, grasses and plants.
- House dust mite allergy: reaction to the droppings of house dust mites.
- Dog allergy: allergic reaction to similar proteins in dogs.
Although the symptoms of different allergies may be similar, cat allergy is unique in the way the allergens spread and how long they linger in the environment.
Conclusion
A cat allergy is an immune reaction to allergens produced by cats, especially the protein Fel d 1. This protein spreads through dander and saliva and can remain in the air and on surfaces for long periods of time. As a result, people can experience allergic symptoms even without direct contact with a cat. A cat allergy can develop later in life and is often mistaken for other allergies.
