Grew up with an outdoor cat in a suburb with backyard. Would let her in when she wanted and out when she wanted. She would occasionally follow us on a walk without any invitation or leash. We were a little surprised "Do cats do that?" I think first time we tried to shoo her back but then we realized it was fine and just let her come with us. Worst that happened was one time a dog scared her up into a tree but she came down eventually. A neighboring family were not so lucky. Theirs kept getting run over by cars (Not because of walks just because of being outside).
