I just wanted to add that making an outdoor cat into an indoor one isn't all that bad, especially if there is anohter cat in the house to keep him or her company. Tilly was six months old when I got her, and had been a stray so she was very used to being outside. But when I brought her home she didn't mind because she had Bassett to play with! (Nutmeg wasn't here at the time). My mom also had a stray that showed up at a year. He still tries to get out sometimes but he understands what "NO! GET BACK" means so he doesn't try to get out that much at all. In fact, all four of my mom's cats are outdoor cats made indoor! Just make sure there is lots of places to look outside - maybe have a bird feeder out a window to keep the kitty entertained, and lots of furniture and stuff so they have places to exercise. I think two cats are better for indoor because they chase each other around, therefore getting more exercise. I hope all this rambling makes sense.. I just finished a take home exam and I'm a bit fried!!!
