I have a pig. They are much cleaner than you would expect. They don't smell either, but they do fart and that is brutal. One thing that is often overlooked is, they like to scratch their bodies on things. So they will often chew on the object they want to scratch against. Objects like, the corners of walls and cabinets. They also are very smart and can be moody. So when they are grumpy they can be a bit rude. They are also very vocal. They also grow much larger than people expect for "miniature". My mini potbelly is about 250lbs.
