Oh boy, I really can't offer any advice. Hearing your stories, I see how lucky I really am. As I have older cats, when I go to bed, they go to bed and don't make any noise until around 7am when I don't get up in time for work or when Speckles decides to play with her mousie from Catmandu at 5am. But I also bought my condo in a cement highrise so that helps. I was on the second floor of a wooden building before and had 3 toddlers above me. Arrrghhhh, try that on for size. I'm sure the rugs will help, if not maybe you could introduce your neighbour to ww.drugs.com....HA HA....just kidding. Good luck!
