Crystallized cat litters are formed from a silica gel. This gel is absorbent and also provides odor control. The silica used in these products is similar to the desiccant that is often found in the pouches packaged as a preservative with foods, medications, and other consumables that can be damaged by excess moisture.
Silica-based cat litters provide an option for those who prefer a non-clay litter. They tend to produce less dust than clay litters, but some cat owners become alarmed about the possibility that the litter may prove dangerous to their cat if ingested in large amounts.
