People get this idea because Ginny is always described with cat like features and stuff. Like for example:
Ginny was curled up like a cat on her chair, but her eyes were open; Harry could see them reflecting the firelight ( OotP, 479)
Hope that answers your question. There are many other mentions like this in the Harry Potter books toward Ginny. I think that Ginny's animagus being a cat is very likely or her patronus being a cat of some kind! 😄
yeah, she can be catlike....
and if anyone dares say she's crookshanks
(which I have heard)
I would like to know why she could be going upstairs with Harry and Ron and Hermione while chasing gnomes in the back yard at the same time.
and if you make any reference to the movie, the actress for Ginny does rather have catty features if you think about it.
