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. | Because of the difficulty for some clients in getting their cats to take pills, the development of this flavorable suspension to mix easily with their wet food has made compliance and efficacy of flea control a lot easier. Getting felines to take medication can always be a challenge. When not accepted in food, many clients have found mixing in various tuna or clam juices, oil, broth, gravy or sardines another way of administering this and other medications. As mentioned in my product review on program tablets, this product works best when given with meals for maximal absorption as well as before fleas are firmly established on the pet and in the home. It works by preventing development of flea eggs and larvae by in essence sterilizing the adult fleas who happen to bite the animal. The product does not kill existing adult fleas and must be combined with other products like Capstar or topical Advantage or Frontline in pets with active flea populations. I find it works best as a preventative before flea season. Many clients will chose to use this and other flea products year round due to the warming of the climate and the unpredictability of the flea season. I give this product an overall rating of a 4 with an ease of use and taste a 5 and efficacy a 4. |
