Took us about 3-4 days with Aurora, about the same for Akira. Very easy to tell when they want to go out to potty and when they just are screwing around. We have an open dialog with them that they better have to potty and if they do to ring it again, 90% of the time if they ring it again, they have to. Of course they are smart enough to screw with us, but we love them anyhow. Better than the scratched up door that we originally had.
