Harry Potter/Characters/Animals and Pets

Hedwig (Gizmo)
Harry's faithful pet snowy owl, and aside from Hagrid, first friend in the magical world.

 * She also gets unhappy when Harry uses another owl for messages.
 * Empathy Pet
 * Eyes of Gold
 * Pride
 * Red Oni, Blue Oni: Blue to Pigwidgeon's red.

 * Swiss Army Tears: An inherent Phoenix ability.

Aragog (voice by Julian Glover)
One of Hagrid's pets, an Acromantula who lives in the Forbidden Forest with his mate and thousands of children. In Chamber of Secrets, Hagrid, while a student at Hogwarts, cared for him when he was young, and Aragog was accused by Tom Marvolo Riddle of being the creature living in the Chamber of Secrets. Years later, he tells Harry and Ron about the creature living in the titular chamber, then sics his sons and daughters on the two (don't worry, they escape).


 * Back for The Dead: In Half-Blood Prince.
 * Cool Pet
 * Giant Spider
 * I Owe You My Life: Hagrid cared for a young Aragog after he hatched and later got him to safety in the Forbidden Forest following Riddle's accusation. The two maintained contact, which saw Hagrid getting him food and a mate. As such, Aragog forbade his children from ever harming Hagrid.
 * Keeper of Forbidden Knowledge
 * Red Herring
 * The Scapegoat: For what the Basilisk did. To add further insult to it, Acromantulas hate and fear Basilisks.
 * Spiders Are Scary
 * To Serve Man: A species trait, though never seen doing so himself. Aragog tells Harry and Ron that he never ate humans, as repayment for Hagrid's kindness. His children, on the other hand...

Voldemort's right-hand pet snake.


 * Chekhov's Gunman
 * Face Stealer / Kill and Replace:.

Crookshanks (Crackerjack)
Hermione's pet half-Kneazle cat.

"Ron: Hermione, I hate your cat."
 * Amplified Animal Aptitude: He is able to find Neville's list of common room passwords, understands enough English to understand Ron saying that Scabbers is in his bag,, and knows right away that
 * Cats Are Mean: Subverted.
 * Demoted to Extra: He does appear in the film adaptation of Prisoner of Azkaban, but his "constantly trying to eat Scabbers" subplot is cut out.
 * Evil-Detecting Dog: The first thing we see him do in the books is pounce on Scabbers, Justified, because this is a species trait for Kneazles as a whole.
 * Spanner in The Works: In the film adaptation of Order of the Phoenix, he breaks the Extendable Ear that Harry, Hermione, Ron, Fred, George, and Ginny are using to eavesdrop on the adults' conversation downstairs.


 * What Happened to The Mouse?: Hermione doesn't take him on the Trio's journey in Deathly Hallows and he's not mentioned to be at her parents' house or at the Burrow either.

Pigwidgeon
Ron's pet owl, sent to him by Sirius as a replacement for Scabbers.

 * Mix and Match Critters: Half bird, half horse.
 * Off With His Head: Narrowly averted thanks to Harry and Hermione's meddling with the Time-Turner.
