Flea control and prevention involves:
If your cat has just picked up fleas, we recommend a fast-kill approach using products such as Hartz® UltraGuard Plus® On Pet sprays, powders, and shampoos. These parasite-control products have active ingredients that work immediately, killing fleas fast.
If the number of fleas is great and you have noted a flea problem on your cat before, choose a more thorough Hartz treatment to ensure that an infestation does not grow.
Prevention is the best method, especially if you know your cat is in areas where fleas often thrive, including your yard. Infestations that start on your cat can also start growing in your home. If left unchecked, such infestations can continuously produce biting adult fleas that not only endanger your cat but also you and your family.
