I agree with Catwoman. The scoopable litter is excellent and as long as you're really good about scooping, you won't have a problem with odor. My boys' litterbox is in my bathroom, which is about the size of a matchbox, so odors could easily take over. I scoop twice a day and I have no odor problem.
Good Luck, I hope your Mom lets you get two babies. I'll bet you that it won't be long before they capture her heart, too.

Oh, I forgot to mention-when I was growing up, every time I wanted a new pet or anything that required responsibility, I would always try to show my mom how responsible I could be with other things and prove to her that I could handle it. You know, keep your room extra clean, do your chores without being reminded and most importantly, keep those grades really high. She will realize that you are serious and can handle the responsibility.
Hope you get your kitties soon!
