I have to agree with everyone here. I have four inside/outside cats and I very much wish they were inside only. My first 2 cats were inside/outside cats before I knew better. As the other cats came along, they were also inside/outside cats as it's almost impossible to have inside/outside cats as well as inside only cats. I have had to lock everyone inside if there's a vet visit or if one of the cats has had surgery and two of my cats have actually make their paws bloody from trying to get out, so I haven't tried to make them indoor only cats. Yes, I have had 2 cats die from being hit by a car and another miraculously survive being hit by a car, which is absolutely awful. That's why I want them all to be inside only cats but I don't want them to have to be heavily medicated so they're happy inside. So, at the moment, they are let out at 7am and come in for dinner at 5pm and stay in until the next morning. This is not an ideal arrangement but I feel I have no choice at the moment.
