Bests & Worsts Reviews from Amazon

I've had 5 boxes of this litter delivered from Amazon and the performance is terrible. This isn't the same litter that I is stocked at big box stores. I purchased the exact same type at Fred Meyers and Walmart and that litter performs great! I don't understand why there is any difference purchasing the "exact same" product from Amazon, but there is, and it's disappointing. The litter I've received from Amazon is considerably larger sized sand granuls, it is darker in color (wet in appearance), and lacks a quality clump and odor elimination. I thought maybe it was a bad batch and I would work through it. After 5 orders I've given up on amazon. The exact same product I purchase at my local stores is NOTICEABLY better litter. It's lighter in color, drier, clumps much better, and vastly improved odor elimination. Yes, I know it sounds crazy or odd, but there is a difference and that is my experience with this litter from Amazon. SEE THE PICTURE ATTACHED. The litter on the left, with the large UPC code on the top of the box is from amazon. I usually don't write a review unless I have a great experience or an experience that differs from the average user. Unfortunately, this amazon purchase was highly disappointed and perplexing as to the difference. I would NOT order or recommend anyone order this litter from amazon.
