| Vet Review | 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. |
