Rocky just shed a few days ago, and today I noticed that one eye has a dent in it. Both eyes appear to be the same except for the dent in one.

He balls up his shed tight and neatly, so I can't tell by looking at that. I think it's dehydration, but it's hard to tell. The humidity drops to the mid 40's now when I'm not around to mist, but he always has plenty of fresh h20 .
