Crookshanks. Crookshanks was Hermione Granger's pet cat. He was half-Kneazle, as evidenced by his lion-like appearance, ability to solve problems on his own without aid or teaching, and clear dislike of and ability at recognising untrustworthy persons (even if they are transfigured).
Etymology. The name Crookshanks seems to refer to the cat's bandy legs, from crook, meaning "a bend", and shank, a term for the lower part of the legs. It is likely to be derived from the Scottish surname 'Cruikshanks', which is pronounced in exactly the same way.
Mrs. Norris, the cat of Hogwarts caretaker, Argus Filch, is a long-haired striped cat with red eyes and first appears in the first movie, “Harry Potter and The Sorcerer's Stone.” She is portrayed by a Maine Coon cat in the movies. You will most likely see Mrs. Norris following Filch around the castle.
Crookshanks is named after Hermione's cat in "Harry Potter." In the book, Crookshanks is a female, ginger tabby. In real life, Paw Placement's Crookshanks is a gorgeous grey and white male kitten with a little "crook" in his tail.
Hermione drank the potion and turned into a cat man
Did Lily Potter own Crookshanks?
Has JK Rowling confirmed that Crookshanks was the Potter's cat? No, she hasn't. It's very unlikely that she will, as this (entirely fan made) theory's only basis is that he liked Sirius (in the books, this was omitted in the films) and hated Scabbers.
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.
No, McGonagall is not Filch's mom. There is no evidence to prove this and it is canon that McGonagall does not have any children of her own. There is no aspect which even remotely suggests that Filch could be her child.
Norris – The caretaker Filch's skeletal gray cat slunk around the castle for seven books. Besides shooting sly glares at misbehaving students, her most exciting adventure was getting petrified by the basilisk.
Scabbers was Ron Weasley's pet rat. Passed down throughout the family, by the time he came to Ron, Scabbers was living up to his name with patchy fur and a distinct preference for sleeping.
Harry's owl Hedwig is a two-foot tall Snowy Owl. (Portrayed as a female, it's actually a male - you can tell because it's pure white.) Ron Weasley, Harry's friend, also has an owl, named Pigwidgeon, a Scops Owl.
A teacher who taught the skill did not need to be an Animagus themselves, as shown when Professor Dumbledore, who was not an Animagus, taught Minerva McGonagall how to successfully become one.
In the Shrieking Shack, it is revealed that Crookshanks befriended Sirius Black, an Animagus wizard who can communicate with Crookshanks while in his dog form.
How did Hermione get away from transforming into a cat after drinking Polyjuice Potion? Well, she didn't get away easily, anyone who read the book would know she had to be in the hospital wing for several weeks. The transformation was a slow process,change in eye colour, removal of furry facial hair.
It was actually Professor Dumbledore (then a Transfiguration teacher) who taught her how to do this. When she completed all the steps, her Animagus form turned out to be a silver tabby cat, with what appeared to be square spectacle markings around the eyes.
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?
McGonagall was also a skilled member of the Gryffindor Quidditch team. After graduation, McGonagall became an employee for the Ministry of Magic in the Department of Magical Law Enforcement where she met her husband, Elphinstone Urquart.
He took particular pleasure in taunting Hermione Granger, who just happened to have Muggle parents. Malfoy called her 'Mudblood', a very grave insult referring to a wizard or witch born to non-magic parents.
Rose Granger-Weasley was the daughter of Ron Weasley and Hermione Granger. She attended Hogwarts for the first time in the same year as Albus Potter and Scorpius Malfoy. Unlike the boys, Rose was sorted into Gryffindor, following in the footsteps of her parents.
In 1994, Death Eater Peter Pettigrew milked the venom from Nagini's fangs and used it, along with unicorn blood, to concoct a dark potion, which allowed Lord Voldemort's shattered soul to regain a rudimentary, but physical form.
Mrs Norris was born sometime prior to 1984, and became the pet cat of the Hogwarts school caretaker, Argus Filch. She formed an unusually strong bond with her owner, and often alerted him to any misbehaving students almost instantly.
Physical description. As a human, she was a beautiful and desirable woman of East Asian descent, with long black hair. In her animal form, Nagini was a large, green snake, roughly twelve feet long and as thick as a man's thigh.
