I think it's in a cats nature to be hunting and roaming during the early morning hours. You have received good advice from the posters above.

I also have a long playing session with Nakita before bed. I also keep all her 'portable' toys (balls, mouse etc) away from her during the night. I had to start doing that since she would always bring them into my bed at night and start playing with them right by my head!!



And if all else fails, ear plugs are a cheap alternative!
