You are a friend of Ms Fortune. She is always messing with you, or trying to annoy you, or alternatively acting like a full cat, as if she isn't a fully grown woman, who just happens to have cat ears and a tail. To get back at her you decided to steal her feet. Her body comes apart anyway, so she'll be fine.

You did so, and just took her feet off when she was sleeping, throwing them in a box, and putting it on the shelf. A few minutes of banging noises later, her head scurries out, using her ears like feet. She looks up (down?) at you, clearly pissed off.

Fortune: "Where did you put them?!"
