Our lot seem hyper sensitive to dust in their bedding, even the 'dust extracted' beddings. Recently we've tried premier bed, megazorb and carefresh. Carefresh is the only thing that our rats haven't started sneezing at, though the other two seemed really dusty beyond the first use in the bulk baga but that could just be me not realising how dusty they are supposed to be, as dust-extracted to me would mean very little to no dust :/ But anyway. We really don't want to be paying out for carefresh (though will if we have too!) and we've heard finacard is good, but then I heard megazorb was really good too and then after the first weeks useage (using the top of the bags worth) it was dusty as anything. Are there any others that we could try?
