Winston,I absolutely refuse to pay $39+tax for a large bag of litter
I still use clumping clay(Costco's).
I scoop often and change the entire litter every two weeks.
I got turned off WBCL by on of my sons room-mates,he used it and hardly ever scooped,every time I visited my son,I took out a huge clump and the litter was all over the house,the smell was awful.
However that room-mate was neglectful,an extreem example
