Mrs. Norris

Sorry if this has already been mentioned, but I was wondering if
anyone had any ideas about Mrs. Norris and, consequently, Argus Filch.

Out of all of the HP characters, I feel that Mrs. Norris and Filch
(and McGonagall, but that's another post!) have been seen quite a bit,
but explained very little.  I don't recall ever hearing about how
Filch came to be at Hogwarts, or anything about his attachment to Mrs.
Norris.  Why does she have a human name? Could she be someone who had
been irreversibly transfigured, or an animagus who got "stuck"?  I'm
always suspicious when JKR omits background info on characters like
this.  Any thoughts, guys?
