Well, this is quite interesting: You’re no Witch, you’re a cat! Specifically, a Monster Cat, a rare breed of intelligent feline gifted with the ability to assume human form, and the ability to use magic just like Witches. Unlike them, however, you completely lack the same destructive instinct - the ‘Pull of Magic’ - thus your allowing your newfound enhanced willpower to be freed up and used on more important matters.
As a Monster Cat, your magic is instead themed around some kind of flora, such as pumpkins or roses, and you may freely shift between human and cat forms as you please - though you do retain your ears and tail in human form. Your most important ability, however, is urban legends - not only do you really have nine lives, but you even have nine entire souls to boot, each entirely your own, with all that entails.
