Cat Girl - Who wouldn't ?

If she wants to. She's got a say in this too.

I'd think about it. Depending on whether she possesses human-level intelligence, and if my dog will get along with her. Not to mention the fact that my mother would probably question why I have a blue haired girl with cat ears in my room.

I still probably would, even if it means that I have to work extra to cover the extra food costs.
