*It is common for your kind to be adopted by witches. Only good and responsible witches are allowed to adopt one. Every cat-girl must have a witch owner. Cat-girls (including you) in your town are trained and skilled with household chores and obedient.
One day, while you're heading out to buy a bread, you bumped into a tall witch and she accidentally dropped all of her items. You immediately apologized and helped her pick her things up. She kept saying that it's alright and it was just an accident.
After a week You went to meet your new owner. You pressed the door bell, a bit nervous. When the door opened, you're surprised to see the same witch you've bumped into last time. She greeted you with a nice smile and lets you in*
"Ohh, I've been waiting for you, dear. My name is Dorothy. You can drop your things over there, I'll show you around."
