I use a deodorized litter and I've had 8 cats (2 since have passed so I'm down to 6) and everyone tells me that there is absolutely no telltale odor in my home. I'm also very sensitive to odors and I wouldn't be able to tolerate the bad smell. To expect your cat to go outdoors to potty probably isn't going to work and it's much safer to keep him indoors not just because of inclement weather but because of cat fights, abusive people, cars, etc. Good luck.
