Who’s does it affect her?
Anthro Cat
The trio retches, one after the other. First Ron dashes off to a stall to heave his guts, then Hermione rushes to another. Harry somehow manages to stay at the sink and finish his glass, but Hermione is too busy gagging in the stall to witness anyone else’s transformation.
She feels like her stomach is tied into a pretzel, and her entire body itches uncomfortably. She looks down at her fingers in horror as they bulge and bend, gradually morphing into a new shape. In shock, Hermione watches her hands grow stubby, unlike any human hands she had ever seen, and then a ripple of tabby fur sprouts from them. She feels the growing fur under her sleeves, and she wriggles clumsily out of her shirt.
Staring at her chest, she can only watch as the fur spreads down her belly, thick, soft, and slightly lighter in color. As it envelopes her small breasts she twinges with pleasure, but keeps her eyes locked on her body. She pulls the waistline of her pants to peek underneath as her pubes become soft and fuzzy, and blend with the spreading fur. The hair filling her thigh gap feels strange, but comforting.
She starts to hear a soft crackling, and realizes that her hearing is improving. Along with that, her ears shift up the sides of her head and grow pointy like a cat’s. Hermione reaches a hand up tentatively, and accidentally brushes past a patch of whiskers sprouting from her cheek. Her ears twitch and she jolts, overwhelmed by the sensation. Suddenly, she loses her balance and falls forward, catching herself on the toilet as the joints in her legs invert.

A squeal escapes her, and from her tailbone sprouts a long dexterous tail. It pokes out the top of her pants, forcing them lower on her hips, and it whisks the air with a lithe gracefulness. Through the daze of her mutation, Hermione knows what must have happened. What she had thought was human hair was actually cat hair, and she has become an anthropomorphic cat!
