Nestlé Purina scientists have demonstrated a proactive way to significantly reduce the active levels of the major cat allergen, Fel d1, at its source in cats’ saliva.
Fel d1 is an allergen produced by all cats – regardless of breed, age, hair length, hair color, sex, or body weight. Produced primarily in cats’ salivary and sebaceous glands, Fel d1 is transferred to a cat’s hair and skin during grooming, then dispersed in the environment via hair and dried skin flakes.
As many as one in five adults worldwide are sensitized to cat allergens, with up to 95 percent of reactions caused by Fel d1. People often manage the allergens by limiting or avoiding exposure to cats.
In research published in Immunity, Inflammation and Disease, Nestlé Purina scientists discovered how to safely neutralize Fel d1 in hair and dander by incorporating an egg product ingredient containing anti-Fel d1 antibodies into a cat’s diet. This ultimately will reduce active Fel d1 levels in the environment while also maintaining normal allergen production by the cat, without affecting the cat’s overall physiology.
