Yes, Kdall, the lions ate straw just like they will do in the future. It is written that the lions shall lie down with the lambs and eat straw. Nothing is impossible with God. Your faith isn't strong enough to believe this? Are you a Christian if you don't believe the Bible?

Michael there is no reason why lions, or any animal for that matter, would have sharpened teeth if they were meant to eat plants. I assume that you are aware that carnivores have sharp teeth specifically because they need to rip and tear meat off to eat? Not to mention that their digestive tracts are shortened because they don't eat plant matter, and lack the necessary bacteria (think probiotics commercial; those kind of bacteria) to break down the vegetation.
I don't believe that God does things like this, no. It goes against all logic and reason. I am positive that Noah's ark is a parabolic story, and it's purpose is to teach, not to act as history.
Now in regards to the verse you referenced about lions and lambs eating straw together, that too is metaphor. It means that all people, even fierce enemies, will in the end be peaceful with one another and all fighting and killing will cease. It does not literally mean that lions and lambs will lay down together and eat hay. Jesus was called "the Lamb of God." But I don't think you believe that he was literally a baby sheep, do you? The Bible is heavy with symbolism
