Are you aware of the sheer destruction a 100lb pig can do?
Furthermore the "Teacup" pig was NOT named for it's size but because it was discovered they enjoyed drinking tea. A supposed miniature or teacup pig can get to be 350lbs!!! I butcher REAL pigs long before 350lbs and let me tell you, they aren't cute or "pets". They STINK, are beyond stubborn and can destroy anything they put their mind to.
Think goats are hard to contain? Get a PIG!
