There is a relationship between asthma and cats, as cat dander can trigger acute attacks of asthma. Asthma is an allergic disease, a chronic inflammatory-reactive disease of the airways. In many patients, exposure to cat dander leads to persistent airway spasm and airway hyperreactivity, which causes a range of clinical symptoms, such as wheezing, shortness of breath, chest tightness, shortness of breath, and widespread croup can be heard in the lungs. In addition to having allergies to cat dander, asthmatics are also allergic to adult mites, cockroaches, pollen, grass pollen, paint, feed, milk, eggs, and fish. Therefore, asthma patients must identify their allergens and try to avoid contact with them in their daily life to avoid triggering asthma.
