Mrs Norris: A Character Study

[heidi]

No: HPFGUIDX 1048

Mrs Norris:
We are introduced to Mrs Norris in Book 1; she is, we believe, Filch's cat, and
she helps him in catching mischief-makers in and around the castle.
She is probably able to "notice" Harry when he's under the invisibility cloak.
She appears on the Marauder's Map, listed as "Mrs Norris".

Topics for discussion:
1. Is she really a cat? We've met so many other unregistered Animagi - how do we
know she isn't one as well?
2. Why is she the only animal to appear on the Marauder's Map?
