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.

I have started to use this product over the past several months and have mixed feelings about it. A big advantage is the ease of administering the beef and pork flavored tablet but it should be administered on full stomach. And while it avoids the oily liquid pesticides on the back that many clients don ' t like, if a pet is allergic to beef or pork this is a big disadvantage. The best thing about this product (which is similar to Capstar) is the quick kill of adult fleas working within 30 minutes and being almost 100 percent effective against fleas within 4 hours of giving it, and lasting for a month!!! (much longer than a Capstar pill.) A big problem is not only the expense but it also has no tick coverage. In my experience and opinion, I have also seen several dogs vomit when given this pill and it is really not supposed to be used in patients with seizure disorders, which is also a concern of mine in terms of safety. Along the same line, it is not supposed to be used in pregnant or nursing females, as from what I understand when the product was tested there were supposed loss of litter during pregnancy, poor weight gain of puppies and vomiting, the latter symptom which I have seen in clinical practice. In general I am always a little worried about products not approved for young puppies, as the puppies have to be at least 14 weeks of old, according to the label use of this product. It is not a cheap product, and for the above reasons I don't use it often even though it is tremendously effective against fleas. For the reasons stated above, I therefore give this product an overall rating of 2 with effectiveness (for fleas) of 4, the ease of use a 5, and the taste a 4. I still prefer Front line, Advantage and K9 Advantix despite the oily spot because of the increased coverage of parasites, and my concerns about safety

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.
