Other than a litter box, which is gross, cats are way, way less work than dogs. I adore dogs as you know, but they want to be with you all the time and to do things with them all the time. Cats can just chill for a while, although they like to play and snuggle too. They are much less needy. And a kitten is nowhere near as destructive as a puppy! Cats don't need to be walked, ours are indoor only so no need to be let in or out, and will generally entertain themselves until I come up to them to play. And no need to house train/potty train. They just do it. Unless they spray, in which case there may not be any training them out of it. Get a female, especially your first time. And their jaws aren't big enough to do major chewing damage, although they will scratch furniture. Then again, I may be biased since vampire kitty still doesn't come out of the bedroom.
