Pretty litter- safe to use or it causes cancer??

The amorphous silica on that page is glass. Silica litter probably contains some other atoms besides silicon and oxygen to make it less fragile, more absorbent, and help guarantee that none of the silicon and oxygen atoms present will be crystalline silica. But it will still look a lot more like the glass structure than the crystalline ...

Is Silica Litter Safe? | Dutch

Meanwhile, amorphous silica gel litter, also known as crystal litter, is safe for pets and humans. Amorphous silica gel litter doesn't contain carcinogens. It is non-toxic if ingested or inhaled—although it may cause GI issues like vomiting and diarrhea— because it doesn't contain crystalline silica. Of course, if you're unsure ...
