When I'm away at work dcat sleeps happily until 7am never disturbing dh. When I get home she will jump all over me at 3am. It's driving me insane. I've been known to jump out of bed and tell her to pack a bag she's leaving. 
I've shut her out and she has left deep scratches in our bedroom door, I've hung up a blanket so she can't instead she'll dig up the carpet when I put a blanket on the door and one on the floor she will sit outside and howl so in every situation i'm woken up.
She must really really dislike me! I can't shut her in a room downstairs because she'll tear the place apart. Boy cat is as good as gold it's just her. I'm tired. Is there a miracle cure for this witching hour?!
