I thought one of my balls was dead today...he was laying motionless with his head kinda twisted into the ground cover with his mouth open...i flicked the glass, nothing, i reached in to get him out and he started moving. But he is acting very strange. He lays almost upside down with his head up in the air and mouth open. I dont know if anyone has ever seen this and could tell me what is going on. He's got water and was just feed 2 mice about a week and a half ago, and i got them new mice today, haven't stuck them in there yet, dont know if i should. He doesn't look like he's in shed mode, idk, thought maybe someone could explain. All environmental conditions are unchanged for the last 3-4 months, dont see how that could be it either.
