All my cats are outdoor cats. I live on a very quiet road in a very quiet neughbourhood, and it is perfect for the cats.
But still, I am always happy if a cat does not venture too far and comes home quite often.
Tosca, my semi-feral cat, sometimes coes not come home for days on end, or at least, does not show herself to us (we have a cat flap, so she can come in and go out at nicht without us knowing). I simply have to accept this is how it works with her, she pines away if she has to stay indoors. She once got injured and had to stay in for months, and she got so depressed I even considered putting her to sleep. She had an open wound, so she really could not go out, but she was desperately unhappy. She even managed to escape once, still with an open wound and wearing her cone collar.
In the end she had a skin transplant and the wound finally healed. So now she is out and about again, which is as it should be, but I do worry about her.
