Mine don't even get free run of the house. I have a cat room with scrubbable walls and laminated floors, and the only furniture is cat furniture, which I change out when they skank it up. A carpenter built out the closet with ramps leading up to lounging shelves and two hanging 'baskets' for them to nap in. I replaced the door with a screen door so they can talk to us and don't feel isolated. In the summer the securely screened windows give them all the outdoors they need.

It's amazing how happy and secure they feel in there, it's truly their place. And I don't have to get nuts every time my husband leaves a door standing open. All of my cats are handicapped, they wouldn't stand a chance outside and I'd even be worried if they had access to the whole house. One of the blind ones would probably fall into the sump pump or something else horrible. They stay in their cat room, where they're happy and safe.
