At least your cat knew where home was, because she's a smart cat. Cats that have never been outdoors are not as street educated and have a greater chance of getting lost or injured.
Maybe now she has it out of her system. At ten years old, she soon will have it out of her system. She'll be less curious about the outdoors and satisfied with the creature comforts of home.
My two ten year old girls have no interest in going outside. I've had them since they were three weeks old, born outside, and they have many opportunities to go out. When I leave the front door wide open they'll walk up to the threshold, sit and look around outside, but that's it.
They know they have a good thing here, because the outside cats are always trying to get inside.
They don't want to lose their territory, they want to protect it. They probably think, "He might let those cats inside and put us outside, we don't want that"
(I would never do that)
At the time I got them, I didn't want any pets. I thought I'd get them to an age where they could be adopted. Then I got attached to them and thought I'd keep one and let the other be adopted, but couldn't decide which. Ten years now and I still haven't decided. One will drag my sock into the living room and I'll say, "You're the one I'm taking to the shelter" Then the other will knocked things off the sink, and I'll say the same to her.
Let's face it, after ten years, neither are going.
