well she turn into a cat because the hair was that of a cat not human
when jk Rowling wrote the books, there was never a mention of an animagus polyjuice potion. however, in the second book, it does state that when you use the pollyjuice potion, you cannot try to turn yourself into an animal, or else something will go totally wrong. Hermione learned this the hard way when she accidentaly put cat hair in the potion instead of the girl's. she got stuck in a half cat, half human state and it took forever for her to recover.
The real Bellatrix Lestrange never really broke into Gringotts. Hermione used the Polyjuice potion because she was suspicious about the way Bellatrix was behaving in the Malfoy Manor because when she asked Hermione where she had got the Godric's sword she was really worried. They thought there might be a Hocrux in Bellatrix's vault, and there was. THIS TELLS NOTHING ABOUT HER WAND!
Harry and Ron went into Slytherin Common room to see Draco Malfoy, disguised as Crabbe and Goyle through Polyjuice potion, to question him secretly if he was the Heir of Slytherin. Hermione stayed behind in the toilets because she accidentally used a cat hair for her potion, and it turned her face into a cat. Hermione was supposed to be disguised as Pansy Parkinson.
