The trio decided to sneak into the Slytherin Common Room to relieve Harrys weird obsession with Draco Malfoy. They took polyjuice potion in the womens bathroom stalls, using hairs of Crabbe. goyle, and millicent bulstrode. Harry turned into Goyle, Ron turned into Crabbe, and Hermione turned into Millicent Bulstrodes cat. "Oh no!" Hermione cried mid morph. "Youre not supposed to use animal hairs!" But by the time Ron opened the stall door, Hermione was fully a long-haired cat. They kept her in the dorm room with them for the next six years, and when they graduated, Harry and Ron got a flat together, quit magic, and split the pet deposit.
