My daughter has owned her guinea pig for 4 months and I noticed that her guinea pig was not eating the Timothy Hay. I tried different brands, Oxbow and Kaytee from the pet stores,and he was just eating the little flowers and leaving the rest of the hay. We ended up just scooping it all out and throwing it away. I noticed that the hay was also very dusty, which did not help my spring time allergies. We decided to try out some Timothy Hay from the KMS Hayloft. I was researching on the online discussion boards and many guinea pig owners say that KMS Hayloft has the best Timothy Hay. So we just received our box and I am really impressed with the hay. It is fresh and soft, and our guinea pig loves it! No more wasted hay that is thrown away and I can actually handle the hay without sneezing:)
