I call it “Disneyfication” as well. Disney may not make “live” animal shows any more, but others have taken it up.
One thing that I have noticed is that human feelings and emotions are attributed to the animals. “The mother coyote is worried that she might not find enough food to feed her cubs,” that sort of things. Do animals worry? Do they feel proud? It’s fairly subtle until you start to pay attention. I think that this has contributed to the misconception that animals are just people in fur coats! Plenty of people these days haven’t spent much time around domestic animals, either. They aren’t aware that cows, pigs, and horses can kill you.
We were at Yellowstone several years ago, and yes there are signs all over the place warning people not to approach the animals. A park ranger there told me that bison kill more people in Yellowstone than bears do.
It’s like I always say, “Your pet cat would kill you, if they could.”
