Vet Review | While this product offers an economic alternative for killing/repelling fleas and ticks for 5 months, as well as preventing the development of flea eggs into larvae and adults, I have personally not found this product effective in my experience and opinion. The clients I have spoken to who have been pleased with this product have found it more effective as a flea preventative, rather than once an infestation already exists, where other products such as topical front line or advantage would be preferred. I have also seen that in some dogs local skin irritation and hives can occasionally occur in sensitive pets, which usually resolve once the collar is removed. I also have concern for cancer and neurological effects with exposure to any prolonged pesticides. While it is a nice benefit that the collar works even when wet, because of my concerns about overall efficacy and safety, I do not recommend use of this product. I give it an overall rating of a 2 with an efficacy a 2 and ease of use a 5. | 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. | 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. |
