I've been sick with the flu and haven't checked on him for a few days. My husbands been feeding all of my critters for me and reported they were all fine. Today I came to check on Leonard and he was in a full shed the only shed that he was able to get off was his head so I sprayed him real good and came back an hour later. He was in his cool hide not moving I lifted his cool hide off of him his back was arched and the shed had not come off. I picked him up and I felt movement inside his body and he was making a noise( it almost sounded like when a humans stomach growls) then he proceeded to open his mouth and shallow hard several times I thought he was fixing to regurgitate his food on me. I assisted him in getting the rest of his shed off and he seems a little more active. Do you guys think he's sick what was that noise I was hearing and why was he opening his mouth constantly, he's not aggressive at all so I don't think he was trying to bite me. Help.
