@Cizzzi, we NEVER recommend buying a pig from a pet store. They are bred and raised in horrible conditions, with the breeding sows kept continually pregnant until they're too old to breed, and are then killed. The baby pigs are often missexed, and have parasites or illnesses. The baby sows are often pregnant. When you buy a pig from a pet store, the store will just order another one from the same source, so you're just condemning another pig to the same fate.
As @stray hares says, people don't NEED pigs, they just WANT them. I understand that. I want them too. But you can wait until one needing rescue is available. You'll be saving a pig in need, and freeing up a space for another one to be rescued.
