Great for Gerbils
I got my gerbils the little corner loo and this sand and they really love it. When it's clean sand they roll in it a lot to groom, and then they love sitting in the sand pit to eat their food. It does become their toilet too but I make sure to clean it out every day so that they have clean sand to groom in once more. Being desert animals I think the gerbils are really at home with some sand in their enclosure.
