I didn't really know where to post this since it is kind of a story and kind of a question. I have a 15 year old cat I got when I was just four. Most of her life has been spent outside (I live in the country). For a long time she would disappear. Up to 2 years at a time. We would think something had to of happened to her then she would show up again and stay around for a few months and then disappear again. During this time If you brought her into the house she would go nuts and look for any way out. Then one day about 6 years ago she came in on her own and has stayed in ever since. She has no desire now what-so-ever to go outside. If you take her out (she won't go outside on her own) she will immediately go around the side of the house and up the poles to our second story deck where she will sit by the screen door and meow until let in. I have always wondered what brought on this change.
