I have Miss Princess my pet pig. And have had pet pigs for the last 15yrs. Dont get one from slaughter house. Your intentions are good but as they havent been socialised it will be more of a problem. They are usually sent to the abbatoir as a part of a contract so they probably couldnt sell you one anyway. It is common misconceptions that they are dirty, they stink and that they will eat anything and everything. Miss Princess has free reign of our property and has picked one spot down the back that she uses as her toilet, she doesnt dig the garden and knows that her food goes in her bowl. We have young kids who she loves to bits. They do need a mud patch in summer as they get badly sunburnt and they use the mud as a sunscreen. They are an amazing pet. Find a local piggery and try and buy either a week old one that you can bottle raise or a weanling that is still young enough to socialize. They will quite often sell you a runt. There is also Minature pigs advertised if size is an issue, but with the right socialising and training even the large whites (which is what Miss Princess is) can make fantastic pets. We had our Doris for 9yrs and she was a wild piglet when we got her and we all had to take a few days off from work and school when she died. She would even carry the peg bucket for me when I was hanging out washing and sit by my side when I was working in the vegie patch, she chased birds out of the vegie patch and the crows away from the baby lambs, she sat with the kids at the school bus stop and was there waiting for them in the afternoon.
