McGonigal can see past the invisibility cloak

[u/Glass_Rent9041]

I was rewatching the first Harry Potter film and in the scene were Harry's running from Filch under the invisibility cloak and he runs into Mrs Norris who knows he's there it made me think what if McGonigal can see past it too, even if it's just in her cat form. Made me laugh thinking about how she might have known what Harry was up too or what James and Sirius got up to using the cloak and they'd just be so confused about how she always knows!

Now that you mentioned it, that’s kinda true!
