oh i have one of those kitties too, my sweet Lexie, as we say i am sure she is digging all the way to China, that is a long way from where i live lol, and yes it is always about 5 or 6am in the morning in our room, actually i have trained her not to scratch at all when i am present, she is getting the message, just pees and runs, and i give her so much praise, and she does it quite often now , even sometimes when i am not present.

But for the upstairs litter box in the mornings, well that is a different story, i think she is hungry and telling us to get up and feed her, so she makes a big deal out of it, kitties don't you just love them at 5 in the morning lol.
