Thank you for sharing your feedback. To clarify; have you tried World’s Best Cat Litter™? One aspect that World’s Best made sure not to overlook despite their original approach is giving up standard clumping abilities that have become the staple of many cat litters. Many times when going with non-traditional materials companies will have to give up clumping ability or at least it will be significantly weakened in effectiveness. This can be detrimental to the overall odor controlling capabilities of the product, as clumping has been known to provide significant support in locking in cat waste odors for long periods of time. That isn’t the case here, as this company proudly boasts that they still retain excellent clumping in all of their products that are intended to do so. We find this approach very refreshing.
