I know it's not the best pic, but here he is!
Nightmare has been here just 4 days, and already he seems perfectly at home. He is active in the evening, and early morning, and during the day he has been doing his sleeping curled up in his hammock. Today, I wanted to clean and refill his water dish, and when I removed the lid, I thought for sure he would hide, but he stayed put, and didn't seem bothered. I am taking that as a good sign, and hoping that it means he feels comfortable, and secure in his new home.
