Every ingredient in this formula has been naturally derived. It contains plant-based ingredients that are safe for regular and consistent consumption by your cat. Unlike competitive products that try to break down the hairball itself, this product attacks the root cause of chronic vomiting, so that hairballs are easily passed through the cat’s system instead of being thrown up. It’s natural ingredients allow you to use weekly, to prevent future vomiting. In addition, we have performed palatability tests to confirm that our natural flavoring is something your cat will desire to consume!
