I love Oscar and thank you for adopting her, but if you love your cat these days, please, please do not let them out. Besides fleas, ticks, coyotes, West Nile virus, EEE, rabid racoons, they can also be hit by a car or any other multitude of misfortunes. I know you are a loving owner, but think how badly you would feel if she never came home again. Times have changed, cat owners have to change too.
