Breny~ I used to keep my cat's litter box in the bathroom next to the toilet in my apartment (b/c that was the only logical place for it), and didn't have any smell issues. Supposedly, using baking soda in the litter helps too, but I'm not sure if it really does or not. I know how you feel though; you don't want people walking into your home and sniffing and saying "there's a catbox here somewhere"
. You might try the crystals; I just haven't b/c they seem more expensive to me and we have to watch our pennies these days
