Nestlé Purina has developed the first and only cat food that reduces the allergens in cat hair and dander. Purina Pro Plan LiveClear is a 100% complete, nutritious and balanced dry cat food that has been shown to significantly reduce the allergens in cat hair and dander in as little as three weeks when fed daily.
The breakthrough product stems from more than a decade of research dedicated to finding a safe, effective way to improve quality of life for cats and their owners.
As many as one in five adults worldwide are sensitized to cat allergens, therefore limiting interactions between owners and their cats. Current methods for managing cat allergens often include limiting time with the cat, isolating the cat in the home or removing the cat from the home altogether.
"Many people think that cat hair is the root of their problem," explained Ebenezer Satyaraj, PhD, immunologist for Nestlé Purina Research and lead investigator for the research," but it’s actually what’s on it – the major cat allergen called Fel d 1, a protein that cats produce naturally in their 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.
The key ingredient in Pro Plan LiveClear is a specific protein sourced from eggs. When cats eat LiveClear, the protein binds to the Fel d 1 and safely neutralizes it in the cat’s mouth. By reducing active Fel d 1 in the cat’s saliva, it reduces the allergen that is transferred to the cat’s hair and dander when they groom, ultimately reducing the allergen in the environment without impacting the physiology of the cat.
Pro Plan LiveClear will be available online and at pet specialty retail outlets in the United States in April, with other markets to follow later in 2020.
