Use Allerpet cat dander remover to gently cleanse the fur of Fel d1 (potent cat dander found in saliva, dead skin, and sebaceous gland secretions), urine residue, and hitchhiking outdoor allergens - all of which can trigger allergic reactions to cats. Allerpet is recommended by allergists and veterinarians and has been scientifically proven to reduce dander. Allerpet is non-irritating and non-toxic and may be safely used on cats of all breeds and any age, including kittens beginning at 10 weeks.
