Most people I know have this same problem. At 2am sometimes earlier sometimes later actually any time after i fallen asleep Rooney attacks me feet . The loser wakes me up because he pounces with his whole body on both of my feet at only the slightest of movement. He does it to my friends too when they stay at my house. Its a good way to wake up and not be able to fall back asleep. But kitty is happy purring loudly and calmed down .
