Peter Pettigrew was killed by his own silver hand, which was given to him by Voldemort as a punishment for his past failures. During the Battle of Hogwarts, when Pettigrew hesitated to kill Harry Potter, his hand turned on him and strangled him to death. This was a fitting end for Pettigrew, who had betrayed his friends and caused much harm throughout his life. **

In the Harry Potter series, Scabbers was able to hide his true identity as Peter Pettigrew for many years due to several reasons. Firstly, Pettigrew was believed to be dead after Sirius Black confronted him, so no one would have suspected him to be alive and disguised as a rat. Additionally, Pettigrew was skilled at concealing his true form and manipulating those around him. Finally, Scabbers was a common pet rat, easily overlooked and not given much attention by others, allowing Pettigrew to remain hidden in plain sight. **

No one noticed that Scabbers was Peter Pettigrew in all the years in Harry Potter because Pettigrew had been presumed dead for over a decade, and his Animagus form as a rat allowed him to hide in plain sight. Additionally, Pettigrew was skilled at concealing his true identity and manipulating those around him. The magical community was also preoccupied with other pressing matters, such as the rise of Voldemort, which may have distracted them from recognizing Pettigrew's true identity. **

No one in the Harry Potter series noticed that Scabbers was Peter Pettigrew because Pettigrew had been living as a rat for over a decade, making it difficult for anyone to recognize him. Additionally, Pettigrew used his Animagus ability to transform into a rat, allowing him to hide in plain sight. Furthermore, Pettigrew took advantage of the trust and innocence of those around him, making it easier for him to deceive everyone, including Harry and his friends. **

In the third Harry Potter movie, "Harry Potter and the Prisoner of Azkaban," Harry did not notice Peter Pettigrew earlier because he had been led to believe that Pettigrew was dead. Sirius Black, who was wrongly accused of betraying Harry's parents, was believed to have killed Pettigrew. Therefore, Harry had no reason to suspect that Pettigrew was still alive and masquerading as Ron's pet rat, Scabbers. Additionally, Pettigrew had been hiding in plain sight for years, making it difficult for anyone to recognize him as a traitor. **

Maintenance cleaning refers to the regular and ongoing cleaning tasks that are necessary to keep a space clean and organized. This type of cleaning involves routine tasks such as dusting, vacuuming, mopping, and wiping down surfaces to prevent the buildup of dirt and grime. Maintenance cleaning helps to maintain a clean and healthy environment on a consistent basis, rather than waiting for dirt and mess to accumulate before cleaning. It is an essential part of regular housekeeping to ensure that a space remains tidy and inviting. **

Heating maintenance and heating cleaning are not the same thing. Heating maintenance involves inspecting, testing, and adjusting the components of a heating system to ensure it is running efficiently and safely. This may include checking for any potential issues and making necessary repairs. On the other hand, heating cleaning specifically refers to the process of removing dirt, dust, and debris from the heating system, such as the furnace or heat pump, to improve its performance and air quality. While both are important for the overall function of a heating system, they serve different purposes. **

Maintenance refers to routine tasks performed to prevent equipment or systems from failing, such as cleaning, lubricating, and inspecting. Repair, on the other hand, involves fixing a broken or malfunctioning component or system to restore it to proper working condition. Maintenance is proactive and helps prevent breakdowns, while repair is reactive and addresses issues that have already occurred. **
