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

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.
