Down with fleas, away with ear mites and onward to defeating heartworm disease. You can stop squirting ear-mite solution and disguising heartworm pills in kitty's food. Revolution (selamectin) is a topical medication that kills fleas within hours and protects your kitty from other parasites.


Revolution (selamectin) is the first-ever FDA-approved topical medication for cats that kills adult fleas, stops flea eggs from hatching, prevents heartworm disease, controls ear mites and treats roundworms and hookworms, according to the Revolution website. Revolution enters the bloodstream through the skin, where it penetrates the tissues to prevent heartworm disease and treat any hookworm or roundworm infections. It also distributes from the blood and tissues to provide protection from fleas, flea eggs and ear mites.


In controlled laboratory studies, more than 98 percent of fleas were killed within a 36-hour period. Clinical field studies showed that monthly use of Revolution provided more than 90 percent control of flea infestations within 30 days of the application. However, if there are fleas in your carpet, bedding or outside, they will still jump on kitty until the flea cycle is complete. Plan on washing bedding, vacuuming and applying a flea product to the inside and outside of your home.


Don't worry about cat scratches because the application is easy. Each tube is one dose and lasts for one month. Simply press the cap down to puncture the seal. Part your kitty's hair on the back of her neck in front of the shoulder blades. Make sure the skin is visible, then place the tip of the tube on the skin. Squeeze three to four times to empty the tube. Don't massage it into the skin.


Never use the product on irritated skin because it contains alcohol. Don't put it on if your kitty's hair is wet, and don't shampoo your cat for at least two hours after the application. Revolution was tested on more than 15 different pure and mixed breeds of healthy cats as well as pregnant kitties; it is generally well tolerated but should not be used on sick, weak or underweight cats.
