I would have to disagree with it being better for them. Most indoor cats I've met are, if not overweight, really out of shape, they suffer boredom and so many of them go a bit stir crazy. Some decide that living inside is better for them, but most really need the fresh air and exercise.
Cats kill things. It's what they do. If you don't want that, don't have a cat.
