The attitude of animals before and after fall

According to the verse below I believe this is how it was in the garden of eden, and how it should be > Isaiah 11:6 > > The wolf also shall dwell with the lamb, and the leopard shall lie > down with the kid; and the calf and the young lion and the fatling > together; and a little child shall lead them. Did the behaviour of animals to man and each other changed after the fall of man and as a result of the fall of man? Or were they influenced by our new nature and attitudes? Or have they been like they were from the beginning? If they have changed, what are the obvious changes?
