My cat smells great, his fur that is. I feed him dry science diet and his kitty liter never smells. Well right when he goes to the bathroom it does for a little bit, but not all the time, every now and again. I have a kitty box with a hard cover on it and I change the filter and have the opening to the kitty box facing the wall. Make sure to leave it far enough away so the kitty can get in.
I hope that helps!!
Oh and don't change their diet a lot. I leave the dry science diet out for my kitty at all times and feed him nothing else. When you change their food a lot it gives them the runs, which will make their box smell worse. Plus the science diet is so nourishing that they don't want anything else, well at least my kitty doesn't. Every now and a gain I give him some pieces of raw steak or something as a snack/treat!!
