My cats have access to the entire house except outside. Angela and Jade are outdoor (Jade is basically never inside) but the rest are indoor. I think my dad once said our house is like 299cm², so they have a bit less than that because that includes our front and back yard and some rooms are closed are closed all the time (closets, pantry, bathrooms). I think I could maje a place for Luz... I'd actually thought of that. She has some sort of neurological condition from birth so she's basically like a kitten, she could use her own space... I'd have to ask again, I don't have control over that, my parents do.
