Bests & Worsts Reviews from Amazon

In Florida we have fleas year round and if it's not taken care of immediately, it becomes a real problem when you have animals. The Cheristin came highly recommended by an online cat community after I reached out for advise. My indoor cats had fleas for nearly 4 months. I tried Advantage ll for 2 months, back to back applications. After that didn't work, I then switched to Revolution (which requires an RX). I later came to understand that the Florida fleas have built up a tolerance to it, and so that didn't work either. Cheristin claims to have 1/2 the pesticide (much safer for pets) than other topical medications, so I was leery that it would work. After dosing all cats just once with the Cheristin and treating my entire apt. with Mycodex Plus Environmental Control (great stuff), the problem is FINALLY solved! Ordinarilly cats run away when I open any topical flea medication - not so with this. They didn't even smell it after I applied it to the back of their necks. Be aware that this medication does not work for anything else, such as worms (which is caused from ingesting flea eggs). I had to use a different medication to treat the cats for that.
