“He's the most intelligent of his kind I've ever met.”
―Siirius on Crookshanks' intelligence
Crookshanks is Hermione Granger's pet cat and a supporting character in the Harry Potter franchise. He was half-Kneazle to explain his lion-like appearance, solving problems on his own and dislike and ability to recognize untrustworty people.
