Pot Bellies are in that gray area. To many they are pigs which means meat. Also while they were not bred this way in America, they were originally an Asian breed and were a backyard meat animal that had a high lard percentage. It's actually a really nice fat. It is also a soft fat similar to wild pigs which is (I have heard) healthier for you. It will literally melt in your hand on a warm day.
They are also super sweet, people oriented, friendly, intelligent, naughty, etc. All the things you want in a farm pet. In my experience it's mostly a cute form of naughty. Some do get nippy though so you have to be careful.
But this is what they were bred for. To be a very friendly backyard pig that produced a high qty of fat to cook with or make soap with and they fit that requirement exactly. They do quite well on backyard scraps/leavings/food waste and because they are small they don't take nearly as much caloric input as a larger hog. And have a far better attitude to boot.
Just because they started out as a meat pig though doesn't mean they don't make FANTASTIC pets. You can clearly raise your piglet in the same fashion as a meat PB would be and then just never eat it. Nothing says she can't be a composter for you that takes in kitchen waste and gives you lovely poop mixed with bedding to put in the garden after it cures. Then she's helping provide food for your family by keeping the garden going and subsisting mostly on that which you would have thrown away.
Also, pig poop smells the worst when it has a high protein output. If she's getting more proteins/fats then she needs you will partially be able to tell because her poop will smell terrible.
