My response to a prompt on the HAPHNE discord. The Cat that Knew: There are rumours at Hogwarts of a cat that roams the halls at night. It's not Mrs Norris, oh no, but rather a ghostly white feline with startlingly blue eyes. Some say it's a sort of apparition, some think it's what Filch dreams of at night but in reality, it's not a cat at all!
