McGonagall as Headmistress

Dear Mr. Filch,

How do you feel about Professor McGonagall as Headmistress? I know you loved Umbridge, so how does McGonagall compare?

Thanks,

Hygienic Hufflepuff

Dear Hygienic,

I am pleased to report that Mrs. Norris (and by extension, myself) has never been happier. While it is true that Dolores Umbridge was a cat-lover, no one understands the needs and interests of a feline better than our current Headmistress, who is one.
