You're the one who brought up "fur baby attachment." I'm not entirely sure what it is, given that this discussion is simply about kids being kind to non-domesticated animals.

I'm sure there are people with unhealthy attachments to animals, and who knows the extent of their issues and how they manifest. But a child who rejects a hobby that, at its core, is the deliberate killing of animals that they find beautiful, isn't that. As a parent, I say it is exactly how a child should be at that age.
