As a former horse owner, I am familiar with this product for horse stalls. It is supposed to have multiple uses though, and small animals is one of them. I am wondering if this may cut down on some of that horrible mouse smell. I am using pine pellet bedding, and although good, it could be better. Here is a link:

I think I will try it. Can't hurt. If anyone else has tried it, let me know how you liked it.
