My Redfoot Murphy usually goes in his hide and sleeps all night till the lights come on in the morning. He has done this for the few years now I've had him. For the past 3 nights though he hasn't gone to sleep, at all. He is walking around his enclosure, banging into the walls, digging, and scratching his shell against things, literally ALL NIGHT! His enclosure is in my room and all I hear is scratching and clunking noises nonstop. He is driving me nuts! I don't know what is going on with him or why he's doing this. Anybody else ever experience this or have any ideas what's going on here?
