Hello,
Cat allergen, the allergy causing material from cats, is not
cat hair, but rather a protein present
in the dander and saliva of cats. These allergens become airborne as microscopic particles, which when inhaled into the nose or lungs can produce allergic symptoms.
You can confirm whether you are allergic to cats by getting allergy testing done.Skin tests and blood tests like RAST are done for this purpose.Pls consult an allergist and get them done.
