A litter of cloned piglets have been born in America.
The piglets are all girls and are called Noel, Angel, Star, Joy and Mary.
Life saving potential
The company that cloned them say that the baby pigs are a major step towards being able to use animal organs in human transplants.
Pig's hearts might be able to be used to save people's lives in heart transplants as they are about the same size and as powerful as human hearts.
These piglets have a specific gene missing which will hopefully prevent their organs being rejected by the human body.
