Becoming an Animagus in Harry Potter is quite rare. It is a fascinating magical ability that requires a lot of knowledge, practice, and skill, and therefore not many wizards are able to achieve this impressive feat. Since transforming into an animal uncovers endless possibilities, all Animagi are required to notify the Ministry of Magic about their status. However, not all of them do so, and there are a few unregistered Animagi roaming around the wizarding world without the Ministry’s knowledge.
