Vet Review | 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. | As most exterminators will tell you, the battle with external parasites and pests is an always evolving battle, as over time, parasites will develop partial resistance to products that had once worked almost perfectly in the past. This has been my experience with some of the older flea/tick formulations and has been reported by my veterinary colleagues and clients alike on occasion. While the older products are mostly still effective, companies are always researching new formulations to stay one step ahead of the development of resistance in the parasites. One of the latest formulations, Frontline Gold takes advantage of newer technologies and now has added an additional insect growth regulator, Pyriproxyfen, to its original formulation, to help enhance the efficacy of the Frontline plus product. The Frontline product is thus able to kill the next generation of flea larvae and eggs even more effectively by breaking the life cycle of the flea. The likelihood of flea immune resistance to this new triple action formula is thus significantly reduced. Given the increasing global warming seen in recent years, the expanding and increasing flea populations in heavily infested areas, however, do require a truly holistic approach by the animal guardian in treating the home, environment and yard for optimal flea control, as it is important to keep in mind that much of the flea life cycle still occurs in the home. While many clients find the more easily applied, self-puncturing tube dispensing method(often only requiring the use of one hand) to the old product, other clients find it difficult to see if all of the product has been dispensed from the colored tube. This new product, however, is quite effective, with only rare topical irritation at the site of the application an only rare complication. With that being said, I give this product an overall rating of a 5, with an ease of application of 4. |
