Inside or Outside Cat?

Indoor only here.....busy road in front of the house, woods in the back. My 14 year old cat has been an indoor cat all her life; I don't even know what she'd DO if she got outside! My hubby's cat was an indoor/outoor cat at his old home, but because of the busy road we decided not to let her roam when they moved into my house. She's old enough (11) that she wasn't spending as much time outside as she once did, so it's worked out pretty well. We do have to be careful about open doors with her, though...I think she'd still like to roam the great outdoors......
