Who is an animagus in Harry potter?

I'm sorry you peeps obviously don't know anything about harry potter, because everyone knows that lupin is a werewolf not an animagus. and you gave no sign we had to choose more than one of the options.

"you need to get your priorities straight" says ron to hermione (which you obviously don't know that).

It is literally impossible for Lupin to be an Animagus. I read up on how to become an Animagus and it involves holding a leaf of a mandrake plant in your mouth for an entire month, straight. Seing as Lupin was bitten as a child, and his transformation taking up 3 days of a month, it just isn't possible.

Remus lupine is a werewolf! James, Sirius and Peter pettigrew are animagus. Rita Skeeter is also an animagus and we find that out in book 4.
