Cats do, in fact, snack on deceased owners. Whether they enjoy it, I can't say.
When I had a cat, I'd fairly frequently wake up with her staring at me, sitting on my chest in the "breath stealing" position. I always imagine her inner dialog being something like, "Morning! Are you dead yet? Can I eat your eyes? OK, not dead yet. Scratch my nose?"
Long ago I had a large orange cat. He would sit on my chest to wake me up. If I didn't wake up he would hook the end of one of his claws into that sensitive piece of flesh the lies between the nostrils, and pull hard. I'm pretty sure he would have eaten me too if I didn't respond to that stimulus.
As someone who gets chased by a dog at least once a month on my daily commute I'm pretty sure they do want to eat me. Maybe a couple are just trying to herd me but I think you underestimate their prey drive.
I don't know if you're being flippant or not, but the desire to eat humans has long been bred out of the domestic animal gene pool (and, frankly, out of most of the wild animal gene pool as well). The dogs who are chasing you almost certainly just want to establish their dominance over you and defend their territories. It's also possible that they want to play.
But any dog that is chasing you, or any other human, needs to be put on a leash. You should have a chat with the dog's owner and point out to them, politely but firmly, that an off-leash dog chasing people s serious liability risk for them. And if the dog doesn't have an owner you should call you local animal control.
A lot of cities have a feral cat problem. Very few have a feral dog problem, because a feral dog problem rapidly becomes a feral dog pack problem, and it turns out a pack of feral dogs is pretty good at hunting people.
Yeah, I live in a third world and the government regularly clean the place out of "aggressive" dogs. I do have dog packs just near my residence and sometimes it's like 7-8 dogs just in front of entry. But they are not aggressive and only pregnant females will follow humans and peg for food.
If the municipality doesn't clean the area it would be a "real" danger against kids.
I'm pretty sure they are not (unless it is a pitbull or something). Most breeds of dogs will not attack humans. They are aware of the difference in physical strength.
Also, if they are real aggressive, I assume a catastrophe has already happened or is in the making (especially with a child?). The authorities have not intervened yet?
