I use carefresh naturals and have never had any problem with it. It's not dusty, it's easy to spot clean, and hasn't molded on me, and my snake loves it. My 6 month old ball python loves to burrow in it and I , obviously , feed him outside of his tank to avoid compaction. I tried other types but the others were too dusty and sucked up more of the humidity. If you use carefresh, I recommend naturals.
yes,I do know that this is a very old thread. But seeing as I often look at the old threads for advice and didn't see any on carefresh other than this one, I decided I should provide my experience to help anyone else who wonders.
