The Science Behind Reducing Allergens in Cats
Research shows that eggs from chickens exposed to domestic shorthair cats can reduce Fel d1 allergens. Fel d1 is the major allergen found in cats, responsible for allergic reactions in up to 95% of people with cat allergies.
What Is Fel d1?
Fel d1 is the primary allergen found in cats. This protein is present in their saliva and fur, triggering allergic reactions in sensitive individuals.
How Our Product Reduces Allergens
Chickens exposed to Fel d1 produce an antibody called "IGY" that attaches to the Fel d1 protein, reducing its effectiveness as an allergen. This results in lower allergen levels in cat fur and saliva.
Our Commitment to Ethical Practices
We ensure chickens are safely exposed to Fel d1, without harm. Through supervised interactions between cats and chickens, we maximize the production of anti-Fel d1 antibodies, all while keeping both animals safe during the process.
