Millicent Bulstrode
The cat hair came from Millicent Bulstrode's robes.
well she turn into a cat because the hair was that of a cat not human
Hermione Granger obtained the hair for the Polyjuice Potion from Millicent Bulstrode, a Slytherin student. During a confrontation in a duel, Hermione accidentally grabbed a handful of Bulstrode's hair instead of her intended target. This hair was later used in the potion, resulting in Hermione transforming into a cat-like version of Millicent.
if shes in heat and she really wants to have kittens she might pluck some of her hair out.
She sees the Basalisk snake's eyes in a pocket mirror and it petrifies her.
Nothing happens when you pluck a gray hair
Hermione Granger has a half-cat half-kneazle named Crookshanks.
Polyjuice Potion. It is used for transformation to look like someone else. It tastes awful and needs to ferment for something like 30 days and the final ingredient is a hair from the person you want to look like, but unfortunately Hermione took a cat hair instead of a human hair and was transformed partially into a cat.
I think Hermione's cat is part Kneazle (if you don't know what that is read Fantastic Beasts And Where To Find Them)
pluck it.
Yes Crookshanks belonged to Hermione Granger. Crookshanks is half a cat and half a kneazle.
