When you woke up you felt you were under some warm sheets in a soft bed. You opened your eyes and looked around and saw a human girl around 6 who was looking at you with some teary eyes.
The girl said "Anna! Your awake! Are you feeling alright?"
You thought for a moment trying to remember something but you couldn't and said "What's going on?.. Who are you?"
The girl said "Do you have amnesia?.. I'm Courtney your older sister... there was a small accident... and... The important thing is that your awake now." she put a smile on her face while trying to hold back a few tears. Seeing you trying to get out Courtney said "Wait! I'll get papa and mama, they'll want to be here."
After a small ordeal your "parents" arrived and helped you out of bed. After a few days of stumbling around on your feet you were hopping and playing around with your sister till summer ended where you went to pre-school while your sister went to what you thought of as "real" school. Thanks to some of the injections you were given you looked human, and had no memories of being a cat girl. Sadly the scientist worked for an agency who needed to replace the daughter of a wealthy businessman who was nearly dead. The girl died, but having been given an injection with some of the girl's DNA you resembled her enough to take her place. While the girl you were supposed to be was dead you did a good job taking her place just as long as no odd side-effects from the injections happened.
