Julie:

You might want to consider purchasing a night vision camera so you can record his nighttime time activities and then watch them when you are awake.

The one I have (under $20) records 12 second clips to the cloud all night long. I can see what he's been up to when I'm having my coffee in the morning. Often, since I am an early riser, it can watch him "live" on me cell phone in the morning, too.

It will alert you when there is activity if you then want to go in there when he's moving about.

There was a discussion I started awhile back on this if you want to check that out.

I also installed a digital counter on his wheel so I can see how far he travels each night. It has been an eye opener to say the least! At some point, that may alert me to his changing health, if the count drops way off for a time.

Again, cheap. There is also a discussion I started, here, on that as well.
