The undead also seem to have calmer and more humane responses when fed properly,while stravation causes aggression and a quick sense to eat anything it can. By my hypothesis,a zombie that is fed by you will have less of a tendancy to chase you,or if fed enough,won't chase you at all. A "full" zombie will even handle live puppies,cats,and be near people without causing harm. It's possible we could just use dead bodies as an anti aggressor against these creatures. I'll attempt to post a photo of one of the specimens once I locate a camera.
Note: Do not attempt to get extremely close to a hungry zombie to feed it,they seem to also get increased strength and speed from stravation.
