Hey, your kids weren't well mannered and housebroken when they were little, were they? Why would you expect a pet to be?
If you take an animal in, be prepared to make accommodations for it and its quirks. It may take a little time and effort but you'll eventually get used to each other - just look at me and that asshole dog Jack. It took some time, but he eventually got me trained to where he wanted me.
