This type of litter does not contain gravel, as its descriptor implies. On the contrary, like its sandlike counterpart, it is merely natural, dried clay. Not all clays are suited to become litter, however. Manufacturers mine, dry, and grind to size only the more absorbent clays. Manufacturers often add a dust-controlling agent to the ground clay to prevent the dust from becoming airborne.
Some manufacturers also add deodorizing agents to block or mask waste odors.
Deodorizers are designed to be strong enough to block or mask the unwelcome odor of feline waste, but not so strong that they deter the cat from using its box or so pungent that they waft throughout the entire house. Sandlike Litter Sandlike litter is made from highly absorbent clay mixed. These mixes often contain sodium bentonite, a particularly absorbent type of clay. Hence, rather than dumping the entire contents of the box, you need only remove the urine clumps and dried feces each day with a metal slotted scoop. You must, of course, top off the contents of the box with fresh litter as needed.
