"I purchased this sand for my two male gerbils. As desert rodents, I figured they might appreciate something that is more like their natural habitat. If you're going to use this sand for rodents, I suggest that you provide a lot of toilet paper to use as bedding, because sand won't hold heat very well, and that you line the bottom of the cage with wood shavings first, to absorb liquids. I gave this a 4/5 because it can sometimes get stuck in a critters' eyes, but as far as sands' go, it's the best out there."
