Our neighbors that used to live across from us had two cats that were indoor/outdoor. And the younger one would always greet me when I came home. He'd even jump in my car and explore around. Unfortunately, we live right by a main/busy road and he was killed.

Our neighbors that live in that same house now have two indoor/outdoor kitties. The orange one is friendly and lets the neighbors 5 year old twins pet him. The tortie, on the other hand, won't be touched. Surprised? I thought not. LOL

Other than that I've only seen a little gray kitty a few times wandering around. I have no idea where it lives and I don't see it often.
