Vet Review | While this collar is marketed to quickly kill fleas, eggs and larvae for up to 8 months and ticks for up to 6 months, I personally have concerns about the safety of the main ingredient propoxar. This powerful cholinesterase inhibitor can cause serious side effects in some pets from digestive upset to respiratory difficulties to neurological problems on rare occasions in my experience and opinion. I am also concerned about human, especially child exposure to such a strong pesticide. While it is a nice benefit that the collar is water proof and works quickly, as well as being an economic alternative for those cost conscious clients, because of my safety concerns and my experience with partial efficacy, I can not recommend this product to my clients. I give this product an overall rating of a 2, with an efficacy a 2, ease of use a 5. | While an economical alternative to the more expensive topicals like Advantage or Frontline, because of safety concerns I cant recommend this product to my clients. Over the years I have seen too many side effects from topical irritation to rare and sometimes severe neurological and/or seizures in some pets. I have also found it to not be as effective in flea control as with advantage or front line. While it is marketed to work against adult fleas, prevent development of flea eggs into larvae and adults, as well as killing ticks for 3 months, once an infestation is in place I have not found this product to be as effective as the competitors in my opinion and experience. One of the nice few benefits I have seen is the killing and repelling of mosquitoes with use of this spot on product. While it is easy to apply and water based, many of my clients have reported irritation reactions as well as greasy fur at the site of application. It is for these reasons that I give this product an overall rating of a 2 with an efficacy of a 2 with ease of use 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. |
