Safari Flea combs are used to control fleas and identify skin and coat problems. Before using, remove any tangles from the cats's hair. Pay particular attention to areas around the cat's ears, nape of neck and base of tail. Between strokes, dip the flea comb into a cup of water with mild detergent. The Safari Flea Combs provide a variety of choices to help detect fleas or dry, flaky skin in the early stages.
