Pixie was like this the first few weeks I had her I was going insane... lol... I was up in the middle of the night 10x a night trying to get her to stop biting scraching and running around like a maniac. What I did was whenever she came up to play I put her off the bed and just kept doing it over and over till she got the hint... Now she sleeps at night with me and knows I'll play when my alarm clock goes off... I'm not allowed to hit snooze though lol.. as soon as she hears it she wakes up and starts meowing at me over my head...
