Well, it's urine and feces so it doesn't smell like cinnamon buns. But cat litter is made out of clay (the scoopable type is treated so it clumps) which absorbs the moisture--and there are litters made out of wood and corn and some other substances if you want to go with something a little more biodegradeable. The box will smell right after the cat uses it (poopwise) but if you keep it scooped, the box shouldn't reek badly. You can also buy an automatic litter box (for one cat, a Littermaid would probably be fine). Cleaning isn't hard. If you're using regular clay (regular litter, not the clumping type) litter, you can put a plastic bag or box liner in the box before you put the litter in so changing taking out the old used litter and putting in new litter is only a matter of wrapping up the plastic liner. With the clumpable litter, you just scoop out the used litter (uring will clump into a ball making it easy to scoop out) and you'll only have to replace litter once in a while. You do have to remember to clean it though--set up a schedule so you don't forget because many cats won't use a dirty litterbox (and they'll start going other places you don't want them to and it is almost impossible to get the smell out and to retrain the cat). Before you get your cat, make sure you have a practical, safe place to keep the litterbox--someplace that is always accessible to the cat, that is easily cleanable (cats will track almost any kind of litter). It's probably a bad idea to keep a the box in an area human sleep or eat or do food prep in (germs). The box also has to feel "safe" to the cat--not too exposed but not so hard to get to that the cat finds somewhere else to go. Hey, if millions of people keeping cats can clean the litter, how hard can it really be???
