Micro piglets are very small pigs that are well-known for their chubby figure, perked-back ears and a short tail with very thick hair. It's basically a cross between a potbelly and Juliana pig. These incredibly adorable pigs are known for being the perfect pet and they only grow to knee height. However, these little piggies are worth way more than their banks. They cost between $1,500 and $2,000 to purchase one of these little guys. It also costs about $60 per month to look after them and a hefty $300 vet bill.
