Good times. Did you know that all animals were vegetarians until Adam and Eve sinned? If you didn't, you should go to the new Creation museum to learn the way that things really happened. Hint: it's not what scientists want you to believe.
The thing that I really fail to understand is why God would want all the animals to be vegetarians. Eating a plant kills the plant. Really, all the animals should have been fruitarians and eaten only things that would naturally fall from the tree and be dead. Eating a living plant is no better than eating a tasty bunny.
