"It was a c-cat hair! M-Millicent Bulstrode m-must have a cat! And the p-potion isn't supposed to be used for animal transformations!"
—Incorrect use of the Polyjuice potion[src]
This cat was a pet cat of Hogwarts student Millicent Bulstrode. Milicent had it with her at Hogwarts in 1992. Hermione Granger plucked a small hair of the cat from Millicent Bulstrode's robes, thinking it was hers. She added the cat's hair to the Polyjuice Potion she was brewing, which resulted in her partial animal transformation after she drank it.[1]
