Variety of BoxiePro cat litters in this promotion.  Pick your favorite (probiotic???), use the Subscribe & Save button to save 40% and you won’t be lugging around heavy bags of cat litter!  I bought so many Tidy Cat buckets pre-Covid that I still have at least five in the basement.  Don’t know about this brand, but try and keep or cancel the S&S.  I’d recommend setting delivery at 2 or more months out so you don’t forget to cancel.
