just bought some of these on the basis that the average cat uses 20lb box of cat litter per month and there are 100 million cats in the us thats $40 per month per cat (i cant believe im writing this lol)that is one hell of a market even if they get only 10% of that.what on earth is the world market for cat litter ,unless i have completely lost my marbles this has to be a screaming buy.by the way i hate cats but i could get to love their shit
