I think your family must have had experience with some down right badly looked after cats in their time. I feed wet food only and the only time their poo smells is when I decide to treat them with tuna or braised steak or something. Otherwise, it really doesn't smell at all. Neither does their wee.
I do clean the litter tray whenever I notice it has been used though. I don't just leave it until set times of the day. Even so, as I said, I have to look at it to see if the litter has been disturbed since I last cleaned it or else I wouldn't know they had been as it really just doesn't smell.
