My cats, indoors
We've had Sophie since she was a kitten. She's never been allowed outdoors, and shows absolutely no interest in going out. Maybe because there are fewer gullible humans to cuddle with than inside our house.
Juniper was a stray we got as an adult, and has been harder to keep away from the doors. We have a boatload of toys for her, so we're all well entertained. She finally gets the point she can't go out; we're still working on the concept of window screens.
I’ve banged this drum before, but please — keep your cats indoors. The Wildlife Society has made the articles regarding the threats posed by (and to) outdoor cats from their current issue of the Wildlife Professional open access. Take a look.
