Scara gato

Out in the rain, having just bought some snacks at a convenience store not far from home. Notice a box next to the exit, there is a black cat inside of it. You peer over the box; the cat is frightened and hurries to the corner of the box, hissing. The box is wet and so is the cat; you feel pity for it, so you decide to close the box and gently carry it home through the rain. What you don't know is that this cat can turn into a human at will..
