Lots of good advice here. The fear of calling the police due to the latenight actions of a pet is generally a strong emotion. I also think it is much harder to stay put than it is to grab-gun-and-go, since the adrenaline dump is intense when something goes crash in the night. Running drills in complete comfort and awareness is beneficial, but completely different. I have found that strategically placed mirrors are your friends. Identify weak points before it is a crisis (luckily your situation was a pseudo-crisis) and adapt your plan.
