Who turned Peter Pettigrew into a rat?

Scabbers was actually Peter Pettigrew in his Animagus form. After tricking Sirius, Pettigrew transformed into a rat and stayed that way for twelve years, from November 1981 to June 1994, living as Percy and then Ron’s pet, Scabbers, in order to hide from the Death Eaters who thought he had betrayed Voldemort.

Who is Peter Pettigrew in the Harry Potter series?

Peter Pettigrew. Originally meant to be the Secret Keeper for James and Lily Potter, Sirius Black thought Voldemort was on to him (he thought that Remus Lupin was a spy), therefore passing on the Secret Keeper to Peter Pettigrew.

How did Voldemort not know Peter Pettigrew was the Secret Keeper?

In one line – Voldemort didn’t know Peter Pettigrew was the secret keeper. Detail explanation – Lily and James knew that Voldemort was after their lives ( and their son’s). So they, after consulting Dumbledore, decided to go into hiding, using the most advanced defensive technique (Fidelius Charm).

Why didn’t Pettigrew tell Lupin about the secret keeper switch?

Because as they were making these plans, everyone – Dumbledore, Sirius, probably the Potters themselves – suspected someone was sharing information with Voldemort. And while it’s strange that Pettigrew avoided suspicion, it seemed Sirius, at least, believed Lupin was the spy, hence why Lupin wasn’t told about the Secret-Keeper switch.

Why did Sirius Black Think Pettigrew would never betray Voldemort?

Perhaps Sirius assumed Pettigrew held them in such high regard he’d never betray them. That doesn’t mean he didn’t suspect Pettigrew would reveal their secrets under threat of torture, but he probably hoped his bluff would prevent Voldemort paying him any attention in the first place.
