My daughters dumpy is having some issues lately that are worrying us. A couple things are hapoens. None is he is sitting with his mouth open at times, he is sucking in his belly at times and he is missing his crickets. I thought maybe he could me molting? I'm just not sure that is it. He seems slower. Not climbing on the back wall anymore. I am going to purchase some calcium for the crickets as I hadn't been dusting them. I have read about the bone disease so will try that. My worry is that he wants the crickets and they go right in front of his face and he lunges, missing every time. They aren't even getting away. Nih's mou hits them but he doesnt suck them in. Mover and over. Any ideas.
