I have 2 guinea pigs. I also have cows and goats. Recently, local suppliers have been selling teff hay, which is supposed to be nutritionally similar to timothy. Our large animals do great on it, and I have over 100 bales in my barn. It seems like good quality hay, well dried and smells good. Can I feed this to my guinea pigs? We are getting it for about $5/bale, so could be quite a savings over hay packaged specifically for small animals.
