Yes, my cats LOVE to be outside. I do supervise the best I can, my 13 year old never wanders and stays right in the yard, my Siamese mix was born outside and was out for his first year of life so he's harder to keep in the yard. I have my handy spray gun ready if he heads for the street, and it's working, he doesn't even go that way, at least for the last few months, but I always have to watch.
