Query: Terrible !!!

Arm & Hammer Super Scoop Clumping Cat Litter Is The WORST!!! It does'nt clump it seems to hold moisture & stinks to high heaven. It also has scented perfume in it , combine that with the lovely smell of cat feces stuck to the rack of my litter maid and you get the picture!! Don't waste your money . Arm & hammer really has nerve to sell this garbage as clumping cat litter.
