OK Ron, I still think it will go nowhere but I will give you a few personal feelings based on my own experience with cats.
Firstly I am against the roaming feral or "semi feral" - some are fed by humans - cat populations that exist round farms near here. I have no idea about ecological damage but according to vets we have spoken to, the cats tend not to be very healthy because of inbreeding. As far as I understand it, there are schems around to neuter these animals.
Our current 3 cats (and most past ones) come from that sort of stock and they have, even if young, known outdoors and want to go outside. They are free to let themselves in and out as they please. I can not accept such animals would ever be contented indoors only and do not believe thier presence outside does any real damage - wish they did with the rat poulation here...
As for a cat that's never been outside, my feeling is they would still want to go outside but I do concede I have never met an indoor only cat to have a personal idea whether they get stressed or not but the first site I look at does suggest they might well do.
