So for example, the rodipet sand says it is made from 100% pumice NO sepiolite and NO attapulgite. They seem to think that is a safe version of sand. And the germans use sand extensively in their cages. However I found it dusty when pouring it out.
So it may be that because people were saying sepiolite isn't safe, that Supreme/Tiny Friends changed their formula to pumice as well.

The negative amazon reviews are all from Amazon in the US. On Amazon in the Uk they're all positive.
