I can only find rabbit food but I heard it's not recommended (or is it)

Where else can I find the recommended kind of Alfalfa? is it worth using?

I live in Toronto Canada

Check organic-minded and livestock feed stores in your area. I find alfalfa meal easier to buy (the stores are just closer). Very useful when making alfalfa tea or wanting to encourage plants to have a growth spur.
