Good day, I am writing you the short letter to advise you that the simply perfect clumping cat litter does not clump in the slightest. Any yarn that our cat deposits just spreads out to a fine mess. This has been going on for months and months and months. Thus I am very very disappointed in the product. It used to be a great cat litter and now with the new formula it is absolutely terrible! During the pandemic we would purchase our cat litter from Costco, and we purchased 2 to 3 at a time. I've already thrown at least four or five boxes into the disposable waste.Sincerely Jerrold Gilbertson Winnipeg Manitoba Canada # [protected] email: [protected]@shaw.ca
