Must be something genetic? IDK. I loved fishing from when I was about 6-7 years old. My dad taught me that if I caught them and wanted to eat them, I had to clean them, so he showed me how, and I did from then on (until the age where if there were boys around, it was easy to get one of them to do if for me, LOL). But it never bothered me. Might be able to do that with poultry if I was absolutely starving. But if I had to kill and slaughter warm blooded mammals, I would probably never be able to eat it. Maybe never again.
