Mine are set at a good time for school days 5:30 – 6:00 but it is a bit early for vacation when I want to sleep in. Luckily they don’t dig at the wall, but they do dig at the bottom of their cage, Stinkers! Sometimes if I am desperate for sleep I have the pellets in a rolly ball all ready so when they start their digging then I can just give them the ball to keep them occupied. Somehow the noise of a rolling ball is less annoying than the sound of digging.
One time they woke me up and as usual I kept trying to go back to sleep. Once and a while there would be a pause in the digging and it would continue a minute later. Usually it is Fern digging but when I rolled over to look at who was digging it was thistle. After watching the little stinkers for a while I realized they were taking shifts. Fern would dig for a bit then Thistle would dig and then Fern would go and Thistle and so on! Little devils! They had ganged up on me!
