so it's very unlikely that they will have "accidents" once you show them where the box is.
As far as scratching goes, if you get a good scratching post or two, and keep putting the cat there when it starts to scratch, you can teach it early on to only scratch where it's supposed to.
Believe it or not, I used to dislike cats myself, then I got a roommate with a cat and the cat took a liking to me. She'd come and sit on my lap while I worked at the computer, etc. When the roommate moved out, I actually missed the furball, then a lady I work with brought this little fuzzy thing that needed a home:

I couldn't turn the poor guy away. Then I decided he needed a playmate and got a second kitten. Two is enough for me though :).
