I live in a condo complex and dogs and cats aren't welcome outside in the common areas. People do walk their dogs around the complex which is allowed as long as they're on a leash. They set out cat traps when they start seeing feral cats hanging around and they post signs warning us to keep our cats inside. All of my cats are always inside so I don't have to worry. I also live near some busy streets.

In my parents neighborhood, many people have indoor/outdoor cats. There used to be a lot of cats that I'd see when I would take walks with my parents. Now I rarely see any cats. Most of the cats have died over the years. Some were hit by cars. When my parents had a cat it was also indoor/outdoor. They still see nothing wrong with this and think that this is how it should be. My dad already told me that if for some reason one of my cats had to live with them that it would have to be indoor/outdoor too.
