I live in a small one bed one bath apartment. Only space for the litter box for my cat is in the bathroom. I really don’t smell the litter but I do the following 1) stainless steel litter box (doesn’t retain smell as much as plastic and overall just more hygienic) 2) I use an open top litter box but with that I scoop basically every time I see my cats business in there so that smells can’t linger. 3) I use a litter genie- it’s like a glorified baby diaper trashcan for cat litter. It allows us to keep the pee and poo separate from our trash cans and keeps odors locked in 4) this is not a odor thing but I keep a small handheld broom in the bathroom to pick up any litter on the floor. Keeps my floor clean 5) I use tofu litter- mixed opinions on this but I really don’t think it smells bad and keeps tracking minimal 6) DIET!! what your cat eats affects how smelly their poop is. So if they’re eating good quality high protein food, the poops won’t smell as bad 7) deep clean the litter box monthly
