Cats are great because, generally, they only demand feeding once or twice a day. Provided you live away from busy roads there's no reason to have a litter tray - just install a cat flap so your cat can go in and out whenever it likes.
I think cats suit Aspies because they're intellectually stimulating - getting to know a cat is always a delicate and interesting process. Cats are always semi-independent, so it's rewarding when they choose to be your friend (even if you are bribing them with food!).
Cats are generally very clean: just as well, as bathing a cat requires gauntlets and a large brandy. Long-haired cats get knotted up and need regular brushing, which they may or may not appreciate.
Problem areas can include: injuries to your pet from fighting with other cats, claw damage to furniture, moulting (shedding fur), worms and fleas, and the cats' adorable habit of bringing in little 'presents' i.e dead mice, rats and birds.
