Also in Zombie movies there is a disturbing lack of nature. I know animals are said to "sense danger", but if Zombies are just after humans (which we have to assume they are, because that's who they freaking chase) then why would other animals fear them? Also if certain species of animals are known to attack humans, why would those animals then steer clear of the zombified humans. I wonder specifically why animals such as Vultures, Buzzards, Bears, Dogs (including wolves & coyotes), Crocodiles, Alligators, Sharks & Hyenas (even flies & cockroaches) aren't more prevelant in zombie movies as all those species are known to eat long dead/decaying animals with no trouble. How can you have a "Zombie Holocaust" and not see any of those animals EVER.....you've got to figure that just because a human is diseased with whatever zombie-juice he got into it doesn't mean some animal somewhere wouldn't eat them.

I would assume the Buzzards, Vultures, & Dogs would have a field day picking apart the walking dead...not like it's hard work to bring down someone who has been dead for weeks or months....and body parts start falling off too....RATS would have a big time eating the undead
