Mine are indoor only as that is all I have known to do plus mine have all been declawed. The two kittens will keep their claws but I plan to keep them indoors - neighborhood is too busy. They do all have access via a catdoor to an enclosed patio that is screened in and they *think* they are outside At least, I think that is what they think since they chase birds and bugs, etc and it has a carpet like grass.
