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. | 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. | This reliable and more economical alternative to Frontline comes from a very reliable company, Elanco. Its main ingredient, fipronil, probably has the most clinical record of experience of efficacy over many years, in killing both adult fleas before they lay eggs, as well as various species of ticks. Its safety is touted by supposedly targeting only the nervous system of the pests. With cats, we always must be careful when evaluating the newer generation of emerging pesticides for fleas and ticks that are coming out, as kitties' detoxification pathways are typically more sensitive than dogs'. Most kitties tolerate this single spot application quite well. In addition to being waterproof, so important for outdoor kitties, this product is easier to apply than most competitors, as well as leaving no pungent or chemical smell like many over the counter competitor products. Most of my clients have found it as effective as Frontline, but not as quick as Advantage. Some clients have complained that it does not seem to repel the ticks, who can occasionally be found attached to the skin before they die. Not only it is important in using products like Easy Spot to prevent flea bite anemia in cats, and unsightly tapeworms, but in recent years, fleas have been shown to carry an increasing number of serious diseases and infections, including Bartonella species, amongst others. Another benefit of this product is that it is labeled as safe to use in pregnant or nursing cats. Side effects, although rare, may include topical irritation at the site of application, lethargy, as well as rare twitching reactions, agitation, and/or restlessness. These are typically short-lived, and fortunately, are very uncommon across pet populations that the product has been used. Some veterinarians and experts have wondered about the recent resistance of fleas to some of the fipronil-based products, but that has not been my experience. I give this product an overall rating of a 4, with an ease of application and efficacy of 4, as well. |
