| - | The major allergen in cats, Fel d 1, belongs to the secretoglobin family of proteins and is, worldwide, one of the major causes of allergic asthma, as it induces IgE responses in 90 to 95% of those allergic to cats and in 60 to 90% of total allergenic activity to cat hair. Symptoms range from mild rhinitis and conjunctivitis to life-threatening asthmatic responses.
