I love this product. I get so much use out of one bag even though it is a little pricey. I think I paid between $8-$9. I'm not complaining though because I'm not even a quarter of the way through the bag and I've already changed my guinea pigs bedding completely twice and I spot clean her cage when needed as well. This product expands so much when taken out of the package and it really traps the smell. I haven't smelled any foul smells since using this product. It's really great and super soft for my guinea pig.
