My cat pawing at the shower door in the master bath. It makes a big rattle as one glass door bumps into the other, and is her way of telling me it's time to get up in the morning. So annoying when it's still dark out. It's not enough for me to open the door to her catio and feed her--I quit doing that. No, she wants me to get up, which I won't do. I do lock her out of the bedroom suite at that point. She'll make a ruckus in the house, but I can ignore it.
