I was cleaning my room when he decided to meet me by the doors of his enclosure. After having a stare down, I noticed his left eye looks a bit sunken in? I might schedule a vet appointment just incase but I want second opinions. His behavior hasn't changed a bit and I was actually going to feed him tonight. He gets his crickets occasionally dusted with calcium with D3 and I need to get some multi vitamin from my partner as it's at his house. I'm about to go look at older pictures of him and compare to the photos I just took. So, does it look slightly sunken or is it just how he is?
