This is such a clever combination of precious and creepy, of wholesome and intriguing. I love that this can be taken all sorts of directions! You can play it as that this cat has like 10 identical siblings, or is an immortal being that stays with people and runs away after learning about the humans there, or it's some God in cat form that riles people up until everyone fights over them, and then makes the sole survivor a member of their cult. 

There's such simplicity here, yet so much room to go with it, and that's awesome!
