When I was visiting a friend in Zimbabwe (in 1995 when it was still a nice safe place) - there was a guy who had a "pet" wharthog. He lived out in the bush and had rescued the baby right after a hunter killed it's mom. He didn't treat it like a pet, but since he'd fed it, etc, it hung around and was perfectly comfortable around people.
(Don't get me wrong - negatives= some stupid human could kill it not knowing it was tame and, I was once walking outside near this guy's place, saw a wharthog, and walked on by it, only to find out it wasn't bumpy -I could have been killed).
