What's the smell, is it urine or poo, or the smell of litter? I would guess yeah it'd probably smell a little like the litter, but I can't see why it'd smell like urine or poo, I can't even smell it when smell the litterbox itself. Maybe depends on which kind of litter you use, mine definitely masks smell. I use Arm&Hammer litter.
urine mostly. the poop dries up pretty quick. but urine scent sticks around. my downstairs neighbour is bad at clean-up routine, you can smell it on the hallway outside of the apartment…
