Do zombies poop?

[Aoi Magi]

Easy.
1.Zombies can't go out in the sunlight because they run the risk of getting burned to death.
2.They go hunting at night.

So even though the city looks clean it's not.
When the cameras show the city they show it in the morning, they show places sunlight can get easily to. They don't show you dark places. Because since those places are dark you can't see much anyway.

So my theory is that zombies poop in the morning in dark dark places where sunlight can't easily get to and hence us not seeing these. The only way they can poop in obvious places like in the middle of the city is if they poop at night. But they have to go hunt at night, so..

zombies are heliophobic?
