Appreciate time spent with your cat when you transition to Purina® Pro Plan® Brand Cat Food LIVECLEAR Sensitive Skin & Stomach Turkey & Oat Meal Formula adult dry cat food. We harnessed findings discovered through over a decade of research to develop an adult cat food that substantially reduces the allergens in cat hair and dander. All cats produce a common allergen, Fel D 1, in their saliva. When cats eat LIVECLEAR formulas, a key protein sourced from eggs binds to the Fel D 1 and neutralizes it.
