I also have problems at nite. We try to tire them out before we go to bed. however it's hard because of our work schedule. I either work 9-5 or 2-10. My husband gets up at 5am for work and at 430am my tabby like to wake us up by head butting, meowing, and if that dosnt work he will jump on a dresser and knock items onto the floor or sometimes he will even makes himself throw up.(never on the floor always on the new carpet) So I can relate. We have had this problem for 3 years now.And no hope of solving the problem. I wish I could help you but I am in the same boat. Good Luck and be patient.Good Luck and be patient.
