Hi. I received a male calico ball python today. When I got him he was pretty cold. I noticed he was doing something with his throat. . It was moving like a lizard and then I would hear a clicking noise. I don't see any mucus on his nose.. no mites.. clear eyes. He seems great besides that one thing. Could it be because he was cold and now needs to adjust to the right temperature? My bumblebee made a clicking noise when I first recieved her.. she was extremely cold and wasn't moving at all also but the noise went away after 2 days... any ideas on what this is?
