Topical cat flea control products work by affecting the nerve receptors of the flea. They are usually applied to the cat's skin at the back of the neck, and are collected in the cat's hair follicles, from which the product is slowly released. Topical flea control products are relatively safe, effective, and easy to use, provided you closely follow the label instructions.
For consumers reluctant to use chemical products on their cats, there are also a number of natural flea control products available now.
Uses imidacloprid as the active ingredient, and is generally regarded as safe for cats and kittens over six weeks of age. Does not kill ticks. We have personally used this product for both adult cats and kittens, and have not seen a flea in our house for several years, nor any side effects from its use. In the "off season," application every two or three months does the job.
Revolution's main ingredient is Selamectin, which is said to kill not only fleas and some ticks, but also ear mites, as well as offering protection against heartworm. Revolution stays in the bloodstream, and should not be used on kittens under six weeks of age. Since it is a systemic product, it may cause allergic reactions in some cats.
As its name implies, this product consists of natural components to help keep fleas, ticks, mosquitoes, flies, and other insects away from your cat. The ingredients are SD alcohol (made from corn), soybean oil, neem oil, lemongrass, catnip, citronella, patchouli, clove, pennyroyal, and grapefruit extract.
For best use, spray your cat's fur thoroughly, including his legs, and tummy. Never spray on the cat's face, however, you could spray a small amount on your hand and carefully apply it to the top of your cat's head. Be very careful not to get it in his eyes, nose, or mouth.
