One day, Bob the everyman wakes up in the morning and goes down to feed his 3 cats, only to find that they have transformed into cat-like people. Essentially they have cat ears and tails, and their hair (inc. body hair) is coloured and patterned like that of the cat they had before. They also have the same cat-like eyes as they had before. Finally, they have much thicker hair across their body than humans tend to get - maybe twice as thick (which still isn't thick, but is a noticeable difference).
However, these cat-people still act mostly like cats. They cannot communicate except in mewling noises, tend to walk on all fours, and mooch around the house just like a domestic cat. They do have slightly improved intelligence - they can now open doors by standing upright and pulling the handle, they will open cupboards to get their food out, and (imagination stretch yes, but this isn't in the scope of the question) use the toilet rather than a litter. (They also avoid... intimacy... in public.)
After ringing the RSPCA, Bob finds that this strange and sudden transformation has affected approx. 1/3 of the world's domestic cats.
Most of these nekomimi act pretty much just like cats, except one. This one nekomimi has intelligence about equal to an average human, and physical ability about equal to a well-trained and athletic human.
Would one nekomimi alone be able to take control of her species from the humans who (in their view) enslaved their people?
