Abstract

Abstract:

A significant portion of the global population is affected by allergies to cats, with symptoms ranging from rhinitis to asthma and respiratory disorders, which have a serious impact on the lives of allergy sufferers. Fel d 1 is currently recognized as the main allergen in cats. It is a secretory globulin primarily produced in the sebaceous and salivary glands of cats, distributed onto their fur during grooming and eventually dispersed into the air. To address the challenge of cat allergies in humans, researchers have attempted various approaches to reduce the secretion of Fel d 1 or control its spread. These efforts aim to alleviate or eliminate allergic reactions in cat allergy patients, including methods such as cleaning cat fur, maintaining a clean indoor environment, breeding hypoallergenic cats, and administering vaccines to cats. This paper provides an overview of the research progress on feline allergens, management and control of cat allergies, and treatment measures.

Key words: allergy, Fel d 1, symptoms, management, treatment
