Normerica International Corp review: Simply purrfect scoopable cat litter not clumping or controling odor

I have been buying your product item #1244567 for many years, but lately the last two 35lb containers that I have purchased through Costco in Albany Oregon in January and March of 2021, have not been clumping, and I am having to add baking soda to help with the odor, or dumping a whole litter box out because it isn't clumping. Did you change your formula?
