Among cats, Fel d 1 is produced largely in their saliva and by the sebaceous glands located in their skin. It is the primary allergen present on cats and kittens. [1] [4] The function of the protein for cats is unknown, but it causes an IgG or IgE reaction in sensitive humans (either as an allergic or asthmatic response).
Fel d 1 is the most prominent cat allergen, accounting for 96% of human cat allergies.

Dander is dried saliva that has flaked off. Since saliva is the source of the Fel-d1 protein, it becomes present on the fur and skin when a cat grooms. When the saliva dries and flakes off, the allergen can then permeate a house. The majority of people allergic to cats are allergic to dander, but some people are sensitive to the fur in general.
