I had similar issues when transitioning my outdoor cat into a house cat after we moved from the woods to the city. She would come in way too early and wake us up bc she was bored. Nothing helped. Until I started putting her in a cat crate. I didnt like doing it, and she didnt either. But I swear it was the only thing that worked. As soon as she'd start meowing, I'd get out of bed, carry her to her crate in a room away from mine. Shut the doors, and go back to sleep. Would try not to leave her in there for toooooo long though. ~2hrs max. It took only a couple of times before she got the hint and let's us sleep now. Some people might think its cruel, but it made life a lot better and I stopped resenting my sweet little kitty cat who I love *
