Vet Review

Another recently available new topical flea preventative for dogs and cats. This new product works by being activated by only the flea's enzyme systems into a flea specific mechanism which paralyzes and kills the adult flea. The company claims that it does not get into the blood stream, but stays only in the superficial skin layers of the pet. Any adult fleas which come into contact with this product are quickly killed so that fleas do not have to actually bite the pet, which is tremendously helpful in those flea-allergic pets, where it only takes a few flea bites to set off an extensive itchy allergic reaction. Another wonderful benefit of this product is that it is waterproof, which is especially helpful in those active outside pets who are exposed to rain or like to swim. This effective product starts working within 12 hours of application, where over 90% of adult fleas are killed. Another excellent benefit of this product is that it also inhibits the development of flea eggs and larvae in the environment, which is a big bonus since much of the flea life cycle occurs in the home environment. While Activyl is very safe and effective for most pets, I have seen occasional rare reactions in sensitive pets, which most commonly is seen as irritation or excessive itchiness at the site of application. While the company says that it is odorless, some of my clients have said that they do sense an odor within the first several days of application, as well as leaving an occasional oily film for the first day or two following application. This film, however usually quickly disappears. The only other very rare reactions include digestive upset and/or drooling/neurological reactions, and certainly if a pet has any chronic digestive weaknesses or history of seizures, etc then the local veterinarian should be consulted before applying the product. I give this product an overall rating of 4, with an ease of use of 4.

A significant limitation of the original revolution product for cats is that it did not cover any species of ticks, which is especially important in those cats who go outside and/or live with dogs where there is increased chance of tick borne infections such as Lyme disease, Ehrlichia and Anaplasmosis in dogs, not to mention the risk of tick born disease exposure in people whose cats bring ticks in to the home. With this new formulation clients get protection against 3 species of ticks. The American Heartworm Society has published that one in 4 cats diagnosed with heartworm disease are indoor only cats, so that especially in Southern, warmer clients, heartworm disease prevention may become as important in cats as dogs. And it takes only a few heartworms to cause significant disease in cats, who seem much more sensitive on exposure to this parasite than even dogs are. This versatile product not only kills fleas before they eggs, but gives additional 6 in 1 protection again ticks, round worms, hookworms, as well as ear mites. THe product is quite quick drying, easy to apply, and not messy or greasy like many other topical formulations. The only down side as to efficacy is in those cases where there is a severe flea infestation affecting multiple animals in a household, where I have found some of the other products a bit more effective in those cases in both dogs and cats, however the vast majority of flea infestations are easily taken care of with this product. Because of the addition of the Sarolamer ingredient for tick control, I would not use this product if there is any history of neurological disease or seizures in the cat. The only other rare side effect I have seen is lethargy and because of its easy to use formulation, only very rare contact sensitivity. With all this being said, I give this product an overall rating of a 4 out of 5 with an ease of application of 5.
