Thanks for the reassurance, Gregg. I tend to freak out about every single little thing when it comes around to my little friend.
I figured I'll just leave it alone especially since I can't figure out what to do about it.
I always raise the humidity to about 60%-70% whenever his eyes get cloudy so he'll have an easier time but I guess he didn't get that piece of this time for whatever reason.
And Wendy, thanks for the concern. I took out all the wet paper towels and everything is back to normal now. Scale rot certainly sounds like a possibility but I only had the extra damp paper towels in for a few hours. He's all happy now especially with a mouse in his stomach.
