Completed to the best I can.
Although, the questions from the point of a house-cat owner are quite hard to answer with the options you offer as answers. Cat management does still apply to me but the answers I could choose from didn't always apply.
If it helps, the main choice regarding keeping the cats indoors is related to breed temperament and character more than anything. Health reasons is also a big factor.
Interestingly, we got a second cat as company for the first cat from Cats Protection. Although we had already decided to keep that cat as an in-door cat, the home-visit person who came said that due to the location of our house, they wouldn't have let us have the cat if we were planning on letting it outdoors because of a 'main' road being in close proximity. This is a road which is, in my opinion, way far enough away to worry about and also, not that busy a road.
