I usually buy from The Hay Experts (used to get small bags of different hays from Animal Magic, but they don't do them now). I think Spenser likes variety, but it's difficult to tell what he really likes. One day he'll favour one type, then it will be something else. Actually he really loves Morrison's straw, but it's got no nutritional value. He's getting to the end of bags of green oat and Western Timothy hay. I was thinking of buying one hay online and another locally to save postage as I'll soon not be working for a while.
