It’s the equivalent of grooming. So yes, it is morally questionable. But so is every “training someone to do a thing”. People just accept it with animals as long as in the end the animal seems fine, because it’s only ever about what seems normal and not about the actual impact. And I’m not saying it’s all a horrible moral crime, just that it’s a large grayscale and can’t be painted as good or bad blankly.

Doing that to random wild animals for no reason does feel rather fucked up to me because until the end point (which in that case is likely just the realization that there’s no danger) it puts the animal under a lot of stress. Not to mention the potential issues with wild animals losing their fear of humans.
