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 difficulties in client compliance in using multiple preventatives in cats for internal and external parasites, a new and comprehensive topical has been developed for kitties. Like the Bravecto Topical product for dogs, this topical for cats is labeled to work selectively on the nervous system of the fleas/ticks rather than mammalian species like the cat. However, on rare occasions even in cats with no prior history of neurological reactions, very rare neurological reactions have been observed in the field, which highlights the cat's unique sensitivity to any pesticide and drug. With the addition of moxidectin to this formulation, this particular product offers additional protection against both roundworm and hookworm intestinal parasites and heartworms, which is an important feature, particularly for outside kitties. While this product rapidly kills adult fleas and ticks who bite the cat, unlike the sister product, Bravecto for Dogs, this product does not repel these external parasites. Another important difference is that the Bravecto Plus product should not be used in pregnant or nursing kitties. The only other issue I have seen with this product is the occasional irritation at the site of application with even rarer digestive tract upset. With all that being said, the product offers excellent coverage against most major internal and external parasites in the cat. I give this product an overall rating of 4 with ease of application of a 5. | Fleas are easily the most common external parasite that plague cats throughout the country. Fleas have been shown to not only cause weakness and anemia in affected cats, but also transmit dangerous infectious diseases, including bartonellosis, an also increasing threat to humans. Cheristin is made with the same main ingredient as Comfortis for cats, and acts uniquely on the nervous system of the flea. Unlike flea prevention tablets, Cheristin starts killing fleas within 30 minutes and almost 100 percent of fleas within 12 hours. With the easy to use applicator, this product has been shown to be quite effective for one month. The most common, yet rare side effect I have seen in cats is an allergic reaction or hair loss at the site of application, and even less commonly vomiting and lethargy. It is an excellent and fast acting, effective product with an overall rating of a 4.5 with an ease of administration of a 5. |
