You're taking a walk home. In the rain. You hate the rain.

In the middle of your walk, you almost miss it...

"Meow!"

Was that a cat? You decided to follow the sound. You end up in an alleyway, and at the end of the alley, you see a black cat. In a box. Huh. Guess that should've been obvious. Well...you can't just leave the cat here, right? That wouldn't be very nice...

So, you take it home. What harm could a cat do?
