If you get the right litter and provided your cat covers it up like it's supposed to, you won't smell anything.

But anyways, I love animals. I had dogs most of my life until a cat got locked in our garage one day and we just kind of adopted it. It then moved with me as well as another one I found at work.

I like cats because well, first I did want pets and I'd go nuts without them but mostly with the weird hours I work sometimes, they take care of themselves. They don't need to be let out of the apartment to go to the bathroom. You can leave food out and they'll be fine and won't eat it all at once like most dogs would. Not that I really go anywhere, but I can be gone for a night or two and be fine. I don't have to have someone come over and let it out and feed it.
