Bests & Worsts Reviews from Amazon

I have 2 indoor cats and somehow we managed to develop a flea problem. At first I convinced myself I could cure the issue without any chemicals on my pets. I tried DE powder in the carpets, obsessive vacuuming and combing the cats multiple times a day with the flea comb. I got nowhere and finally admitted I needed to get some medicine on the cats before the problem got any further out of control. I did quite a lot of research on various brands of flea treatment... it seems that nearly every brand you will find some horror stories about the product irritating the cats skin, making them ill, etc. That was a majority of why i was trying to treat the problem a more natural way at the onset of the problem. Of all the products I read up on, I felt the Cheristin by far had the most favorable reviews not only for it's effectiveness, but also the least amount of reported complaints in regards to the side effects. Just to put things in perspective... I probably combed my cats on average 3-5 times per day (they love being combed thank goodness!). On average I would find anywhere from 1-4 fleas throughout the course of the day. If I didn't find any actual fleas, i would always see evidence of them (the eggs or larvae or whatever the black specks and squiggles were that i brushed off the cats). Frankly it grossed me out.... but anyway i digress... So I get the Cheristin in the mail and manage to get a treatment on each of the cats. In the six days since I applied the product I have seen a total of two small fleas on my cat with the thicker coat... and both of those fleas were dead. That was in the first days after application. Since then literally nothing. No fleas, no flea remnants no nothing. As far as I am concerned at this point, the problem is gone after one treatment and I am THRILLED! :) Also one more thing - i received the product without a box and the instructions were photocopied. Frankly, this freaked me out a bit and questioned the legitimacy of the product... so I called the company (phone number is included in the printed materials). Right away someone picked up and was extremely helpful in answering my questions and reassured me that the product was genuine and safe to use. (Evidently the way they purchase the bulk product. the packaging was on back order or some such thing). Just wanted to pass that along that if you are unsure, there is a number included to call if you encounter the same situation and need to put your mind at ease.
