Highly absorbent, non-dusting, and we change our gerbils definitely rarer than usually recommended - the last time just before Christmas and now again in the spring - okay, they have a large terrarium and are only 2 - but it really does not smell. Only with the dose I'm undecided, the whole bag is too much - I think sometimes 2/3 come back. Man (mouse) can also prima tunnel build in it, just a bit miteinmischen hay.
