[Walknomore]

How do you guys think Walkers prey on animals? I mean we've seen them eat deer but more or less its already been dead ones and in Season 2 while field dressing one Daryl found woodchuck remains. The horse more or less was led to its doom in the first episode. Of course in Fear one took down a dog.  How do you think wild animals deal with the new predators that are now roaming the environment? Which animals do you think would go possibly extinct from Walker predation?
