petting zoo

I know we're cut off from our food supply and we have romantic versions of animals in our heads. So don't want to kill the animals, and we don't want the animals to eat other animals, but we eat meat all the time.  But when people actually walk toward a petting zoo they're terrified. And it's not just the babies. I don't understand why a baby wouldn't actually want to go up to an animal that sees, especially if the animals just sitting there but this is the state we are in. I understand not wanting to be around the poop or the smelly animal but these people are genuinely scared.  The smell didn't bother me after 10 minutes.  Farmer in my blood.
