Although Allerpet Cat Dander Remover is specifically formulated to help remove cat allergens and soften the pet’s skin, it should really be called Allerpet For Cat Owners. Why? - because it helps people who are allergic to cats live with them more comfortably. Because cats produce more dander than any other animal, Allerpet Cat Dander Remover is a liquid damp-wipe product that works hard to bind and remove cat allergens so there will be less of them in your home. It is not necessary to eliminate all cat allergens (something that is nearly impossible to do) to feel better. Even a 50% reduction should help. If you want to reduce allergens even more, Allerpet recommends applying Allerpet Cat Dander Remover every 3-4 days, rather than weekly. Features: Most effective formula for Cat Allergies Can be used on all cat breeds Recommended by veterinarians and allergists nationwide Does not expire Safe for cats of all ages, including kittens over the age of 10 weeks Available Size: 12 fl. oz (355 ml)
