Flea Away (natural vitamin) tablets are formulated for dogs and cats to repel fleas, ticks, and mosquitoes. They work by masking the smell of carbon dioxide, which attracts these pests, creating a natural barrier. This method helps prevent bites, and Flea Away also offers additional benefits like promoting healthier skin and coat, reducing shedding, and supporting joint health. Safe for both dogs and cats, including nursing mothers and their litters. Non-prescription.
