It's getting downvoted because this varies hugely by location. In the UK, the life expectancy is not that different, there are no large predators, so the consensus of cat owners is that cats life richer lives if let out. If you live in the US your cat could be eaten by a mountain lion or coyote.
This is pretty much the same attitude which leads to kids being wrapped in cotton wool, ferried everywhere in giant SUVs and never let outside to play. I find it a bit sad.
dude, it isn't a giant SUV divers that are advocating for indoor cats. they are the same people that hold onto the whimsy that "cats a natural and belong outdoors! :)"
