At a place called Pet Club they always have Ever Clean on sale once a month so I stocked up and I bought 5 25lb boxes of it. I also still have another 25lb box from a previous time. At Petsmart I like to buy the Odor Eaters litter and they also seem to have this on sale a lot. I have a 20lb jug and a 28lb bucket of this. So I currenty have 198lbs of litter. Wow!!!! I must be obsessed.
