SWince I live off a major road, as in ten feet from the window... indoors only. Even if I lived in the middle of nowhere, they'd still be indoors only. I like knowing where they are and what they are up to. There are still dangers out there that are not involved with cars: mean minded humans, larger animals that think my cat looks like prey, disease, etc. If they were evr outdoors, I'd drive myself insane wondering where they were or what they were up to.
