The FURminator® Undercoat Removal Tool for Cats removes loose hair shed by cats and helps keep the coat dirt and debris free. The tool is specially designed to go through the epidermis to remove loose undercoat and undercoat hair without damaging the epidermis or cutting the skin (when used as directed). The de-shedder can help reduce the formation of hairballs in cats as less loose hair is consumed during self-grooming.
