Just curious - Is Cat-Man's 'Kitten' going to show up one day? Her sudden transformation from pre-teen to hot momma sure would be ripe for parody!
It seems it, but puberty does hit hard in some people. I can think of a couple of female friends, growing up, who...maybe it took two or three months, and most of the boys were too young to notice at the time, but Kitten isn't all that unrealistic.
And today, that sort of thing can happen over a weekend, but usually involves parental waivers and some bed rest.
Which is all to say that going there should go with a warning to tread carefully, since girls who might identify with it have more than enough body image issues already, regardless of how it happens...
