Aren't the houses wonderful. Yeah, I kind of thought that they looked like something that would fit into Wizards' World.

I agree with your ownership designations.
Houses of this sort aren't built cheek by jowl. There's land around them which is perfect for privacy and adequate room for kittens to pretend and/or actual hunt in. Plenty of room inside also *grins* for hunting kittens who are hiding after magical flea bathing.
