A friend has been looking into the new silica litters, specifically one that says it can monitor your cat's health. And we've decided NOT to purchase ANY silica litters at all. This is why: ALL silica litters involve some silica dust. We know for a fact that silica dust causes silicosis in humans. Now granted, the amount of dust in the litter is very small compared to the level of exposure in industries that cause silicosis in humans, but our cats' lungs are also very tiny.
This is what the American Lung Association has to say about silicosis in humans:

I also found a very good answer to whether or not to use silica litters on Quora. Her research is good, so I'll let you read it as she wrote it. She did a much better job of explaining things than I could have.

Not taking any chances, here. I'll stick with the corn litter than Hekitty loves.
