Things about the Walking Dead

 There is one thing that bothers me about the premise of the Walking Dead series. (Despite a few of my relatives instance that the zombie apocalypse will be caused by uninformed voters of both parties, depending on who you listen too.)

 Anyway, supposedly some virus infected some person somewhere and he bit another person to infect them and on and on.

 Now the infected persons are dead, except for some little part of their brain which make them want to eat non infected people and pass the infection along.

 In one episode the Rick person was riding a horse, he got away but the walkers ate the whole horse. At least it looked that way. Now why would they eat a whole horse and not eat a whole person?

 But the biggest bother to me is, if the walkers are dead, except for a little part of their brain, wouldn’t their body decay? I mean a rotting body can only stay mobile, supposedly, for a few days before it falls apart.

 And how come there is not a single dog, cat or even a cow left alive? Horses are deer are but no other wildlife. Did the walkers eat them all or what? Hell horses are more tame than cattle.

 At least in the Night of the Living Dead movies there where skeletons crawling around… but how since their brains where dried up.

 I like the Walking Dead series, but come on now, the premise has some serious flaws.
