Personally, I keep my kitty indoors also and wouldnt even consider allowing her to run outside. Not only the safety factor (cars, dogs, and just plain mean people that dont like cats) but they can contract diseases from other cats that an indoor cat in all probablity wont contract. Just my opinion if I wouldnt allow my dog or my children to run outside unattended why would I allow my cat to do so. We recently had as area not far from here where a pet cat contracted rabies and attacked 4 people who now have to undergo treatment. I have a kitty shelf at a window for her to lay on where she can bask in the morning sun and watch the squirrels and birds. A safe kitty is an indoor kitty!
