Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
My cat absolutely loves Greenies. In fact all of my cats did. On Amazon they are y great price as they are expensive at the pet shops. They are supposed to be good for their teeth. My cats are always going to be eating Greenies. Thanks
