Pot bellied pigs are inquisitive animals who require a lot of care and attention. Paris has burned through Chihuahuas, ferrets, and kinkajous in the past, so there's no reason to think that an animal who will undoubtedly root through her precious Manolos will grow old by her side as her BFF.
Pot-bellied pigs were all the rage in the 80s, a decade that had some truly unfortunate trends, but Paris seems bent on resurrecting them all. It's one thing for her to rake up fashion violations like this, but it's quite another to make animals suffer. If we could have the ex-con arrested for being so uncaring, we would.
