Are you gone during the day? Sounds like he needs something to do to wear him out before bedtime. Play with him, HAY, get a laser light and play with him until he is wore out! They love those lights and will chase them for hours!

He still has a lot of kitten energy in him from the sound of it. My Giz will explore when the lights go out at night so I have to have my bedroom Giz proffed or she will keep me awake playing. She has a rather large basket of toys in the living room and I will get up in the morning and they are scattered all over where she played with them at night..

Also, you may want to look into getting some calming spray or something to calm him down until he (hopefully) outgrows this. I would remove the pictures off the walls until he forgets about them being playtoys. He is waking you up because it works! Chester use to wake me up every morning... It took me less than three times to put him out and shut the bedroom door and he stopped that... Even if he sits there and crys and it keeps you awake, do that until he learns... you are awake anyway, right?
