What kind of cat is Hermione holding in the train in Harry Potter 3?

Crook Mountain is a wonderful animal. It's a big ginger cat with a flat face and a fat tail that blows like a bottle brush. Its owner, Hermione, bought it from the Magic Pet Store in diagon alley (1August 1993) because no one would buy it, and it had lived in the pet store for quite a long time before that. Crook Mountain is partly made up of cats and raccoons, so it is very smart and can identify bad people. The most obvious example is Crook Mountain's attitude towards Pettigrew (prisoner) when it appears in the form of a mouse. Moreover, when Harry and Ron make up answers in divination class, it can be seen from the way it stares at them that it can also recognize and disapprove of cheating (Goblet of Fire, Chapter 65438 +04).

Cat raccoon is a very clever cat-like animal. It can quickly smell suspicious objects and make very fierce gestures to them. Once it has a deep affection with the wizard, it will be an ideal pet.
