Harry had the suspicion that she was able to see him even when he was under his Invisibility Cloak, although she may have just sensed someone there but couldn't see, as cats are known to possess highly advanced senses that humans do not have.
There are three possibilities for individuals or creatures that may be able to see through Invisibility Cloaks: Dumbledore; Dementors; and Mad-Eye Moody and his magical eye.
Norris seems exceptionally smart for a cat, to the point that many have suspected she is a cat/Kneazle cross like Crookshanks or an Animagus. However, J. K. Rowling has stated on her website that she is just a highly unpleasant cat. Mrs. Norris's role in the first two films is much the same as her role in the books.
Can cats see through invisibility cloaks in Harry Potter?
Norris and Crookshanks can sense Harry under it, though in fact the cats may be hearing rather than seeing the passage of those within. Peeves also senses Harry, Ron, and Hermione under the Cloak in Harry Potter and the Philosopher's Stone, though it is obvious that he is hearing rather than seeing them.
A fake eye belonging to Alastor 'Mad-Eye' Moody, the enchanted device had an electric blue iris and could rotate 360 degrees in the wearer's head. The eye was able to see through anything, including the back of Moody's own head and even invisibility cloaks, and was the reason that Moody became known as 'Mad-Eye.
Can dementors see through Harry's Invisibility Cloak?
As explained in the 3rd book, Dementors cannot see at all. They recognise the presence of people by sensing their emotions. An invisibility cloak makes the wearer only invisible, but doesn't block their thoughts or emotions. So, these cloaks are useless against Dementors.
Harry had the suspicion that she was able to see him even when he was under his Invisibility Cloak, although she may have just sensed someone there but couldn't see, as cats are known to possess highly advanced senses that humans do not have.
How did Harry Potter's dad get the Invisibility Cloak?
James inherited the Cloak from his father, Fleamont Potter, who inherited it as a descendant of Iolanthe Peverell — a granddaughter of Ignotus Peverell. The Cloak passed down through generations of the family until it reached James and then Harry.
Did Snape know Harry was under the Invisibility Cloak?
Dumbledore was doing James a favour by helping him pass down the Invisibility Cloak to his son Harry. Snape definitely knew because in book 4 when Harry sees crouch in Snapes office, he's in his invisibility cloak. As soon as snape sees the golden egg and the map he says 'potters here' to mad eye. Potters here.
James's Animagus form was that of a stag, which earned him his nickname, Prongs. Strikingly, Harry's Patronus was a stag and his mother Lily's was a doe, a female deer, showing that the family's characters were in harmony and formed part of the same animal group.
Squibs would not be able to attend Hogwarts as students. They are often doomed to a rather sad kind of half-life (yes, you should be feeling sorry for Filch), as their parentage often means that they will be exposed to, if not immersed in, the wizarding community, but can never truly join it.
Although the magical eye was seen as a cameo on the door of Dolores Umbridge's office following Moody's death in Harry Potter and the Deathly Hallows: Part 1, there is no indication of Umbridge receiving it as a gift.
Both Albus Dumbledore and Voldemort were aware of this ancient magic, and Voldemort was known to "despise" it. indeed, Dumbledore was able to willingly invoke a form of ancient magic, a bond of blood charm, to protect Harry Potter so long as he was in the Dursley family's care.
Harry is a descendant of the Peverell family, and Ignotus Peverell was the owner of the invisibility cloak. He passed it down to his son, who passed it to his son, and so on it went for many generations, until it finally was given to James Potter by Harry's grandfather.
The Potters' generational wealth is traced back to their ancestor, Linfred of Stinchcombe, who amassed a great fortune through his medicinal services and inventions of healing potions.
How did Hardwin Potter get the Invisibility Cloak?
To elaborate on Icecreamdif's answer, he inherited it as a family heirloom dating back to Hardwin Potter, who married Iolanthe Peverell, granddaughter of the Cloak's original owner Ignotus. It was passed down to the eldest male of each new generation of Potters since then.
Why did James give Dumbledore the Invisibility Cloak?
Dumbledore, who had searched for the Deathly Hallows in youth, asked to borrow the Cloak from James to study it. After James was killed, the Cloak was left in Dumbledore's possession.
Norris is his wife and since he is a squib, he actually transfigured her into a cat without knowing how to retrieve the curse. So, is Mrs. Norris the wife of Argus Filch?
Mrs. Norris' looming presence in the Harry Potter series is far too magical for her to be an ordinary cat, and there's enough evidence to support a theory that she's a Maledictus like Nagini. Filch's nosy cat appears all throughout the book series and occasionally in the films.
Filch was Hogwarts' caretaker, but he was also a squib - a Muggle born from wizard parents (which may possibly be the case of Jacob Kowalski from Fantastic Beasts as well).
Albus Dumbledore, arguably one of the greatest wizards in history, has been the only wizard recorded who didn't inherit the Parseltongue ability but could understand it. It is unclear how he was able to learn it, however, although he could understand it and imitate some sentences, he was not fully able to speak it.
How does Malfoy know Harry has an Invisibility Cloak?
Goyle/Crabbe had their trunk stored in the same rack that Harry occupied, under the cover of the invisibility cloak. When Goyle/Crabbe retrieves that, the trunk strikes Harry's head and he gasps out loud accidentally, which Draco hears.
Why can mad eye moody see through the Invisibility Cloak?
Moody's fake eye could see through it because that's what it's meannt to do, see through things. And the cloak just makes the person wearing it invisible, it's doesn't work as a shield. That's why Malfoy could hit Harry with spells.
