In every corner of Hogwarts where a first-year dares to tread, you’ll likely hear the swish of Mrs Norris’s tail — Filch’s cat, often mocked, yet seemingly the very reason he breathes. But why does the grumbling Squib, so incapable of tenderness, guard her with such devotion?
As it turns out, Harry Potter fans have a theory far more intriguing than a simple love for animals.
A Cursed Woman?
Some are convinced that Mrs Norris isn’t a cat at all, but a Maledictus — a woman cursed to permanently transform into an animal, just like Nagini. Supposedly, she was Filch’s great love, and when he couldn’t save her, he chose to stay by her side — as Hogwarts' caretaker, at the very place where it all happened.
Or a Willing Prisoner?
Another theory suggests that Mrs Norris is actually an Animagus who chose to remain in cat form forever — perhaps for Filch’s sake. And he, realising the sacrifice she made, now guards her like a priceless treasure. In this light, their strange bond isn’t just friendship — it’s a quiet, tragic love, caught between fur and silence.
Sound mad? Perhaps. But in the wizarding world, the strangest thing is that no one has ever denied it.
