Review on Blue Mountain Timothy Hay (3 LB): Premium Natural Food for Guinea Pigs, Rabbits, and Other Small Pets - Ideal Hay for Bunny Rabbit, Hamster, Chinchilla, Gerbil, Similar to Alfalfa Pellets, Cubes, Orchard Grass by Heather Martin

I know several brands of timothy hay and have used different types. My adopted guinea pig Theon enjoyed chewing Blue Mountain timothy hay in her "hay room" which opens onto a spacious cage. The hay isn't as light green as some I've used, but it's not too dry and she seems to like it. It comes in a large box of crumbly timothy hay. It has no plastic environment and there may be some dust. So far it hasn't bothered me. You may need a separate airtight storage basket. So far I am satisfied with the quality, I will order more.
