What is the source of Fel d 1?

Fel d 1 is a well-known allergen primarily associated with cats. It is a protein found in cat saliva, skin, and dander. When cats groom themselves, the saliva gets deposited on their fur and skin, leading to the spread of Fel d 1 into the environment as the fur sheds or is brushed against surfaces. This is why individuals who are allergic to cats often react to exposure in homes where cats reside, and it highlights the important link between cat skin and potential allergic reactions.

Understanding the sources of allergens is crucial for managing allergies and taking appropriate precautionary measures. In the case of Fel d 1, knowing that it primarily comes from cat skin helps in both diagnosis and advice for pet owners or those living in households with cats on how to reduce allergen exposure. This specific knowledge aids healthcare professionals in recommending allergen avoidance strategies to their patients.
