Potioncat:
If you look at Sirius, Peter and James you'll see lots of images 
that fit their animagi and to a certain extent, that is true of 
Remus and wolf.  And yes, Ginny is certainly described as cat-like 
in many ways.  So I have no doubt she'll become an animagi, but I 
doubt she is one now.

Does anyone see cat qualities in McGonagall?
