I woke up this morning and after about 10 minutes i heard my beardie Jo make like a coughing/hissing/huffing sound. Jo opened her mouth when she did this. Now after about 3 hours later she still does it but through her nostrils? I'm really worried for her and i have no idea whats going on. There is no mucus, her nostrils are clean, nothing in her eyes. Does she have a cold or something? should the heat be higher? Her beard turned black the first time, now it's normal. Help please!
