"I've used just about every product out there with my Gerbils, Mice and Guinea Pigs, this stuff is awsome. The color makes everything look clean, and you don't have the hassel of getting wood shavings out of your fuzzy socks, you still have to change it of course, but it's alot more absorbent and easier to manage than corn cob. The only place I don't recomend it is as a top layer for guinea pigs, I do use about 3 inches under a layer of aspen for them, but for animals that don't dig much if any, this stuff compacts too much, but that's a problem with all of the paper type products, using them together has eliminated the wood shavings tendancy to mildew near the bottom layers, I give this product an A++ in all departments."
