Mom had 'em on the homestead when she grew up. If you wanted pork in the depression era, you raised it. They turned into pets and the kids wouldn't eat 'em. They're a rather smart animal, equal in intelligence to a dog.
I had thoughts about raising some at the ranch, but I know better. I'd wind up with hogs that died of old age because they'd wind up as pets. I'm a meat eater, but I'm not much of a killer. If I had to personally slaughter every bite of meat I ate, I'd be eating a lot more veggies. Once a critter is dead, I've got no problems gutting it and cutting it up. I've never paid to have a deer processed in my life. I just lost my taste for killing, especially something I've raised.
I doubt a lion frets over the zebra it's just murdered.....
