I have 4 cats, one is very prone to fleas. The cats spend their days outside. So far, we have not seen any fleas, but the neighbor's cat is peppered with them. The collars stay on, they smell great and they look really cute. I replaced the collars after a month so they all have fresh and potent herbs (and a fresh new look). I'm very happy with these flea collars.
