Fluffy shook her head at both questions. She didn't live anywhere, so didn't think that question could be sufficiently answered, and she didn't plan on telling him where she used to live. One reason: Because the answer was pretty much the same; Two: Because she didn't feel like talking about her past.
And though she kind of felt like having another fish, growing up she hadn't really had the chance to have cooked fish, so her stomach would most likely upset if she had too much.
Fluffy whipped his chest with her long white tail then acted innocent about it all.
