Where have they marketed as a litter box product? If they have, I'm much more open to the idea. Searching "litter" on that page had no results.

Im so skeptical because I'm under the impression now that the coarse bonzai tree crush wasn't coarse enough and hampered air flow significantly leading to urine damp zeolite that didn't drain into the soak pad underneath the Breeze litter boxes. Or perhaps more accurately: it drains most of it, but some moisture doesn't evaporate.

This clinoptilolite zeolite looks like an even finer crush, which makes me so doubt it'd work, but I'm just going off my previous layman experience.

In comparison, you can see how large (with a lot of room to breathe, which I'm assuming is the difference which matters, but I could be mistaken) these zeolite cat litter pellets are:

All the competing brands use a similar pellet shape. Edit: although I don't know if that's because it's important or if these companies are all using the same source and just slapping their various labels on it.
