Integrity Multicat Clumping Cat Litter is made of 95% Wyoming sodium bentonite clay with 5% Zeolite for extra odor control. No fragrances, dyes, or chemicals, makes this litter great for sensitive cats and people. The low track and low dust formula has excellent odor control and clumps for easy removal. After the clay is harvested, the land is replanted in order to protect the water quality and to create spaces for wildlife, recreation, and farming.
