I am currently feeding my guinea pig Zupreem Timothy Hay when I can find it in the pet stores. I have used Oxbow Orchard Hay, but I mixed it in with the Timothy Hay. I've heard that Meadow Hay is just as good as Timothy Hay. What are your opinions on Orchard and Meadow Hay for guinea pigs? Are there any hazards to feeding too much Orchard or Meadow Hay compared to Timothy Hay? I've also heard that there was Oat Hay. Is this meant for guinea pigs? I've heard that Alfalfa Hay can kill guinea pigs. What about the other kinds of hay that I have mentioned. Are they okay for guinea pigs, or should I just stick with Timothy Hay? There is also a hay made by Oxbow called Botanical Hay. It's more expensive, and I'm not sure whether it's even good for guinea pigs. Please let me know what you all think. Thank You,
