According to the YEC view, did the animals eat the forbidden fruit? Assuming the Young Earth Creationist view that the Genesis account is literal history...

When Adam and Eve ate the forbidden fruit they were condemned to death which caused every subsequent human to bear death's potential. The question is: since animals also die just like each and every one of us, did they also eat the forbidden fruit?
Most adherents to the literal young-earth seven-day creation account believe that when Adam and Eve ate of the fruit, God applied the curse to the entire universe, including animals.  Animals didn't need to eat the fruit to be affected by the curse. From the YEC view, whether animals ate the fruit is irrelevant because they weren't made "in God's image"

Supporting example, from http://www.answersingenesis.org/articles/kw/museum-guide-corruption


  God had warned Adam and Eve that if they ate of the Tree, they would
  die. When God came to walk with them that evening, He punished their
  sin. The earth was now cursed. Death was now part of life; both
  animals and humans would now die (Genesis 3:19; Romans 8:20–22). When
  the first humans sinned, it corrupted all of creation. The ground was
  cursed and would produce thistles and thorns (Genesis 3:17–18).
  Animals began to hunt and eat other animals. Man would now have to
  work hard for food, and woman would have pain in bearing and raising
  her children (Genesis 3:16–17).


The Institute for Creation Research (ICR) says this:


  The animals, not having moral natures, were not guilty of sin, of
  course, but they also shared in the Curse, for they were—like
  Adam—made of the dust of the ground that God had cursed. Like Adam's
  body, their bodies also must return to the ground. Henceforth, "death
  reigned ... even over them that had not sinned after the similitude of
  Adam's transgression" (Romans 5:14). Thus there is death in the world
  only because there is sin in the world.
