Genesis 1:30

And to every beast of the earth and to every fowl of the air and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat. And it was so. That was the food which the Lord had provided and intended for animals of every description, whether mammals or birds or reptiles or any other kind, namely, the tender green grass and vegetation. It follows, then, that neither did man use animal food before the Fall, nor were there any beasts of prey that stalked their prey; they all lived together in perfect harmony and partook of the food which the Lord provided in richest measure.
