If it's an indoor cat you can even jettison the litter box, if you train it at home first. Yes! The skills are transferable!
It helps if you have at least 2 bathrooms in your home for training...and realistically, plan on 30-60 days for the project. It's optimal if you are able to start with a very young cat, but older (i.e. 6yrs, for example) can be successfully trained as well (may take longer).
One possible drawback of this solution is that it's just like having another person on board when it comes to "fill rate" of holding tanks.
