To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Great all-rounder treatment to just use once a month and not worry about. Has a very strong smell once applied, and if you have a wriggly cat like mine it's hard to get them to stay still to apply it to the right spot deep enough in their fur. I've had no side effects though, and it dries quickly enough that if some gets on her outer fur while she's getting away and she tries to lick it, she's fine.
