The stuff itself smelled a little strange when putting it in (I have never smelled carefresh though). I suppose a kind of sharp but woody smell. However, I just leaned over the tank and took a good sniff while putting her food in, and I can't smell a thing; not bedding nor poopy smells. Good so far!
Compared the the coco-soil stuff, it seems to absorb odour better. The real test will be after she's eaten and poops more.
