This is my two year old male panther and the past couple of days I have noticed that his colors are kind of dark and I have caught him with his eyes closed during the day. I know this is a huge sign of sickness or stress but I don’t understand what could be wrong with him. He has a bathing spot, a UV light and a misting water source. I have seen him drink and eat so I think that I’d a good sign. The main thing is definitely his eyes closing during the day. Can someone please give me some advice I am really worried about him.
