I'm new to using Argo, I didn't know what to expect but my mice and myself love it, my mice are happier and healthier than they've ever been, reason I started using Argo was because I have mice in racks that have hoppers and my own muesli mix for the rats was getting wasted by falling through the hoppers and having to change the bedding every 1 to 2 days and filling hoppers up constantly but using argo I've only just filled the hoppers up after a week even though I didn't really need to plus on not having to clean out racks every 2 days or so.
There is a fair amount of powder in the bag but don't worry about that if you avoid collecting it in the scoop wait until you've nearly finished the bag and put the powder into a mixing bowl and ad some water until its thick consistency, don't wet it so its soggy, just enough so it's stuck together and you're not wasting it.
