Hey there!
I have three cats, two of which were my idea. Cats are EXTREMELY clean animals. We've had one of our cats for thirteen years, one for four, and one for six months, and never have any of our cats tracked their waste from their litter box through our home! Do research about the best types of litter that are absorbent and neutralize odors. I'm sure if you do your research, you'll be able to show how willing you are to commit to a new animal.
Best of luck to you!
